About William B. Shockley, Jr., Nobel Prize in Physics, 1956
http://en.wikipedia.org/wiki/William_Shockley
William Bradford Shockley Jr. (February 13, 1910 – August 12, 1989) was an American physicist and inventor. Along with John Bardeen and Walter Houser Brattain, Shockley co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics.
Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s led to California's "Silicon Valley" becoming a hotbed of electronics innovation. In his later life, Shockley was a professor at Stanford and became a staunch advocate of eugenics.
Early years
Shockley was born in London, England to American parents, and raised in his family's hometown of Palo Alto, California. His father, William senior, was a mining engineer who speculated in mines for a living, and spoke eight languages. His mother, Mary, grew up in the American West, graduated from Stanford University, and became the first female US Deputy mining surveyor.
He received his Bachelor of Science degree from the California Institute of Technology in 1932. While still a student, Shockley married Iowan Jean Bailey in August 1933. In March 1934 Jean had a baby girl, Alison; she also had a son, Richard (Dick). Shockley was awarded his PhD from the Massachusetts Institute of Technology in 1936. The title of his doctoral thesis was Electronic Bands in Sodium Chloride, and was suggested by his thesis advisor, John C. Slater. After receiving his doctorate, he joined a research group headed by Clinton Davisson at Bell Labs in New Jersey. The next few years were productive ones for Shockley. He published a number of fundamental papers on solid state physics in Physical Review. In 1938, he got his first patent, "Electron Discharge Device" on electron multipliers.
World War II
When World War II broke out, Shockley became involved in radar research at the labs in Whippany, New Jersey. In May 1942 he took leave from Bell Labs to become a research director at Columbia University's Anti-Submarine Warfare Operations Group. This involved devising methods for countering the tactics of submarines with improved convoying techniques, optimizing depth charge patterns, and so on. This project required frequent trips to the Pentagon and Washington, where Shockley met many high ranking officers and government officials. In 1944 he organized a training program for B-29 bomber pilots to use new radar bomb sights. In late 1944 he took a three month tour to bases around the world to assess the results. For this project, Secretary of War Robert Patterson awarded Shockley the Medal for Merit on October 17, 1946.
In July 1945, the War Department asked Shockley to prepare a report on the question of probable casualties from an invasion of the Japanese mainland. Shockley concluded:
If the study shows that the behavior of nations in all historical cases comparable to Japan's has in fact been invariably consistent with the behavior of the troops in battle, then it means that the Japanese dead and ineffectives at the time of the defeat will exceed the corresponding number for the Germans. In other words, we shall probably have to kill at least 5 to 10 million Japanese. This might cost us between 1.7 and 4 million casualties including 400,000 to 800,000 killed.
This prediction influenced the decision for the atomic bombings of Hiroshima and Nagasaki to force Japan to surrender without an invasion.
Solid-state transistor
Shortly after the end of the war in 1945, Bell Labs formed a Solid State Physics Group, led by Shockley and chemist Stanley Morgan, which included John Bardeen, Walter Brattain, physicist Gerald Pearson, chemist Robert Gibney, electronics expert Hilbert Moore, and several technicians. Their assignment was to seek a solid-state alternative to fragile glass vacuum tube amplifiers. Its first attempts were based on Shockley's ideas about using an external electrical field on a semiconductor to affect its conductivity. These experiments failed every time in all sorts of configurations and materials. The group was at a standstill until Bardeen suggested a theory that invoked surface states that prevented the field from penetrating the semiconductor. The group changed its focus to study these surface states and they met almost daily to discuss the work. The rapport of the group was excellent, and ideas were freely exchanged.
By the winter of 1946 they had enough results that Bardeen submitted a paper on the surface states to Physical Review. Brattain started experiments to study the surface states through observations made while shining a bright light on the semiconductor's surface. This led to several more papers (one of them co-authored with Shockley), which estimated the density of the surface states to be more than enough to account for their failed experiments. The pace of the work picked up significantly when they started to surround point contacts between the semiconductor and the conducting wires with electrolytes. Moore built a circuit that allowed them to vary the frequency of the input signal easily. Finally they began to get some evidence of power amplification when Pearson, acting on a suggestion by Shockley, put a voltage on a droplet of glycol borate (a viscous chemical that did not evaporate) placed across a P-N junction.
December 1947 was Bell Labs' "Miracle Month," when Bardeen and Brattain – working without Shockley – succeeded in creating a point-contact transistor that achieved amplification. Within the next month, Bell Lab's patent attorneys started to work on the patent applications.
Bell Labs attorneys soon discovered that Shockley's field effect principle had been anticipated and devices based on it patented in 1930 by Julius Lilienfeld, who filed his MESFET-like patent in Canada on October 22, 1925. Although the patent appeared "breakable" (it could not work) the patent attorneys based one of its four patent applications only on the Bardeen-Brattain point contact design. Three others (submitted first) covered the electrolyte-based transistors with Bardeen, Gibney and Brattain as the inventors. Shockley's name was not on any of these patent applications. This angered Shockley, who thought his name should also be on the patents because the work was based on his field effect idea. He even made efforts to have the patent written only in his name, and told Bardeen and Brattain of his intentions.
At the same time he secretly continued his own work to build a different sort of transistor based on junctions instead of point contacts; he expected this kind of design would be more likely to be commercially viable. The point contact transistor, he believed, would prove to be fragile and difficult to manufacture. Shockley was also dissatisfied with certain parts of the explanation for how the point contact transistor worked and conceived of the possibility of minority carrier injection. Shockley worked out a rather complete description of what he called the "sandwich" transistor, and a first proof of principle was obtained on April 7, 1949.
This resulted in his invention of the junction transistor, which was announced at a press conference on July 4, 1951. Shockley obtained a patent for this invention on September 25, 1951. Different fabrication methods for this device were developed over the next several years, but a diffusion based/photolithographic procedure quickly became the method of choice for many applications. It soon eclipsed the point contact transistor, and it and its offspring became overwhelmingly dominant in the marketplace for many years. Shockley continued as a group head to lead much of the effort at Bell Labs to improve it and its fabrication for two more years.
Meanwhile, Shockley worked furiously on his magnum opus, Electrons and Holes in Semiconductors which was finally published as a 558 page treatise in 1950. In it, Shockley worked out the critical ideas of drift and diffusion and the differential equations that govern the flow of electrons in solid state crystals. Shockley's diode equation is also described. This seminal work became the "bible" for an entire generation of scientists working to develop and improve new variants of the transistor and other devices based on semiconductors.
In 1951, he was elected a member of the National Academy of Sciences (NAS). He was forty-one years old; this was rather young for such an election. Two years later, he was chosen as the recipient of the prestigious Comstock Prize for Physics by the NAS, and was the recipient of many other awards and honors.
The ensuing publicity generated by the "invention of the transistor" often thrust Shockley to the fore, much to the chagrin of Bardeen and Brattain. Bell Labs management, however, consistently presented all three inventors as a team. Shockley eventually infuriated and alienated Bardeen and Brattain, and he essentially blocked the two from working on the junction transistor. Bardeen began pursuing a theory for superconductivity and left Bell Labs in 1951. Brattain refused to work with Shockley further and was assigned to another group. Neither Bardeen nor Brattain had much to do with the development of the transistor beyond the first year after its invention.
Shockley's abrasive management style caused him to be passed over for executive promotion at Bell Labs, which also felt he was a greater asset as a research scientist and theorist. Shockley wanted the power and profit he felt he deserved. He took a leave from Bell Labs in 1953 and moved back to the California Institute of Technology (Caltech) for four months as a visiting professor.
Shockley Semiconductor
Eventually he was given a chance to run his own company, as a division of a Caltech friend's successful electronics firm. In 1955, Shockley joined Beckman Instruments, where he was appointed as the Director of Beckman's newly founded Shockley Semiconductor Laboratory division at 391 San Antonio Road, Mountain View, California. With his prestige and Beckman's capital, Shockley attempted to lure some of his former colleagues from Bell Labs to his new lab, but none of them would join him. Instead, Shockley started scouring universities for the brightest graduates to build a company from scratch, one that would be run "his way".
"His way" could generally be summed up as domineering and increasingly paranoid. In one well-known incident, he claimed that a secretary's cut thumb was the result of a malicious act and he demanded lie detector tests to find the culprit. It was later demonstrated the cut was caused by a broken thumbtack on the office door, and the research staff was henceforth increasingly hostile. Meanwhile, his demands to create a new and technically difficult device (originally called a Shockley diode and now modified to become the thyristor), meant that the project was moving very slowly.
In late 1957, eight of Shockley's researchers, who called themselves "The Traitorous Eight," resigned after Shockley decided not to continue research into silicon-based semiconductors. After a meeting with Sherman Fairchild and procurement of seed capital from Fairchild Camera and Instrument Corporation, they started Fairchild Semiconductor. "The Traitorous Eight" included Robert Noyce and Gordon E. Moore, who would later leave Fairchild and form Intel Corporation. Other offspring companies of Fairchild Semiconductor include National Semiconductor and Advanced Micro Devices.
Thus, over the course of just 20 years, a mere eight of Shockley’s former employees gave forth 65 new enterprises, which then went on to do the same.... Shockley Semiconductor and these companies formed the nucleus of what became Silicon Valley, which revolutionized the world of electronics and, indeed, the world itself.
While Shockley was still trying to get his three-state device to work, Fairchild and Texas Instruments both introduced the first integrated circuits, making Shockley's work in that area essentially superfluous. Shockley did manage to get the three-state device to work but failed to make it commercially successful.
In 1961 he and Hans Queisser derived the maximal theoretical efficiency of a simple solar cell, subsequently known as the Shockley-Queisser limit.
The firm was sold in 1960 and became a part of ITT in 1968.
Sidelights
Shockley was popular as speaker, lecturer, and an amateur magician. He once magically produced a bouquet of roses at the end of his address before the American Physical Society. He was also famed in his early years for his elaborate practical jokes. He became an accomplished rock climber, going often to the Shawangunks in the Hudson River Valley, where he pioneered a route across an overhang, known to this day as "Shockley's Ceiling."
He was first to propose a lognormal distribution to model the creation process for scientific research papers.
He was an atheist.
Later years
Shockley separated from his wife Jean in the spring of 1954, divorcing her that summer. Shortly after forming Shockley Semiconductor, on November 23, 1955, Shockley married Emmy Lanning, a teacher of psychiatric nursing from upstate New York. They had a very happy marriage that lasted until his death in 1989.
In July 1961, Shockley, his wife, and son Dick were involved in a serious automobile accident: Shockley required several months to recover from his injuries.
When Shockley was eased out of the directorship of Shockley Semiconductor, he joined Stanford University, where he was appointed the Alexander M. Poniatoff Professor of Engineering and Applied Science.
Shockley's last patent was granted in 1968, for a rather complex semiconductor device.
Statements about populations and genetics
Late in his life, Shockley became intensely interested in questions of race, intelligence, and eugenics. He thought this work was important to the genetic future of the human species, and came to describe it as the most important work of his career, even though expressing such politically unpopular views risked damaging his reputation. When asked why he seemed to take positions associated with both the political right and left, Shockley explained that his goal was "the application of scientific ingenuity to the solution of human problems."
Shockley argued that the higher rate of reproduction among the less intelligent was having a dysgenic effect, and that a drop in average intelligence would ultimately lead to a decline in civilization. Shockley advocated that the scientific community should seriously investigate questions of heredity, intelligence, and demographic trends, and suggest policy changes if he was proven right.
Although Shockley was concerned about dysgenic effects among both blacks and whites, he perceived the situation among blacks as more problematic. According to 1970 Census, unskilled and skilled whites had on average 3.7 and 2.3 children, respectively, whereas the corresponding numbers for blacks were 5.4 and 1.9. Because IQ is a heritable trait, Shockley expressed concern that the black population would become progressively less intelligent, countering all the gains that had been made by the Civil Rights movement. Shockley's views on this topic, expressed in his publications and lectures, were based in part on the subsequently discredited work of Cyril Burt. Shockley also proposed that individuals with IQs below 100 be paid to undergo voluntary sterilization.
He donated sperm to the Repository for Germinal Choice, a sperm bank founded by Robert Klark Graham in hopes of spreading humanity's best genes. The bank, called by the media the "Nobel Prize sperm bank," claimed to have three Nobel Prize-winning donors, though Shockley was the only one to publicly acknowledge his donation to the sperm bank. However, Shockley's controversial views brought the Repository for Germinal Choice notable publicity and may have discouraged other Nobel Prize winners from donating sperm.
While the "Nobel sperm bank" issue was in the news, Playboy magazine published in its August 1980 issue a lengthy interview with Shockley. Although Hugh Hefner, the magazine's publisher, was not particularly sympathetic to Shockley's views, this in-depth interview nonetheless provided an opportunity for the professor to clarify his views on eugenics and the social implications of racial differences, and to defend his side of the controversy to a wider audience. In 1981 he filed a libel suit against the Atlanta Constitution after a reporter called him a "Hitlerite" and compared his racial views to those of the Nazis. Shockley won the suit but received only US$1 in damages. Shockley's biographer sums this up as saying that the statement was defamatory, but Shockley's reputation was not worth much by the time the trial reached a verdict.
In his later years Shockley took several precautions to improve his interactions with the media, to little avail. He taped his telephone conversations with reporters, and then sent the transcript to them by registered mail. At one point he toyed with the idea of making them take a simple quiz on his work before discussing the subject with them. His habit of saving all his papers, even laundry lists, provides abundant documentation for researchers on his life.
Edgar G. Epps argued that "William Shockley's position lends itself to racist interpretations". Daniel J. Kevles mentioned that Shockley "invited ridicule as a racist and biological ignoramus". Anthropologist Roger Pearson has defended Shockley, arguing that Shockley’s views were misrepresented in the popular media by journalists who lacked a proper understanding of the topics Shockley wrote about, and that his views were in fact shared by many other scholars who were reluctant to publicly defend him due to fear of being attacked themselves.
Death
He died in 1989 of prostate cancer.
By the time of his death he was almost completely estranged from most of his friends and family, except his wife. His children are reported to have learned of his death only through the print media.
A group of about 30 colleagues, who have met on and off since 1956, met at Stanford in 2002 to reminisce about their time with Shockley and his central role in sparking the information technology revolution, its organizer saying "Shockley is the man who brought silicon to Silicon Valley."
Honors
He received the Comstock Prize in Physics of the National Academy of Sciences in 1953.
He was the first recipient of the Oliver E. Buckley Solid State Physics Prize of the American Physical Society in 1953.
Shockley was a co-recipient of the Nobel Prize in physics in 1956, along with Bardeen and Brattain. In his Nobel lecture, he gave full credit to Brattain and Bardeen as the inventors of the point-contact transistor. The three of them, together with wives and guests, had a rather raucous late-night champagne-fueled party to celebrate together.
Holley Medal of the American Society of Mechanical Engineers in 1963.
He received honorary science doctorates from the University of Pennsylvania, Rutgers University in New Jersey and Gustavus Adolphus Colleges in Minnesota.
Maurice Liebman Memorial Prize from the Institute of Radio Engineers (now the Institute of Electrical and Electronics Engineers (IEEE)) in 1980.
Shockley was named by Time Magazine as one of the 100 most influential people of the 20th century.

О William B. Shockley, Jr., Nobel Prize in Physics, 1956 (русский)
Уи́льям Брэ́дфорд Шо́кли (англ. William Bradford Shockley; 13 февраля 1910, Лондон — 12 августа 1989, Станфорд) — американский физик, исследователь полупроводников, лауреат Нобелевской премии по физике 1956 года. В годы Второй мировой войны Шокли участвовал в создании американской школы исследования операций и в разработке тактики стратегических бомбардировок. В январе 1948 года Шокли изобрёл плоскостной биполярный транзистор, а затем создал научную теорию, объяснявшую его работу. В 1956 году Шокли основал названную его именем лабораторию, которая стала одним из истоков Кремниевой долины.
В личности Шокли сочетались талант теоретика и преподавателя, культ собственного интеллекта и тела, неукротимая тяга к соперничеству и глухота к мнениям и интересам других людей. Жёсткость Шокли стала причиной ухода из его компании «вероломной восьмёрки», положившей начало буму в микроэлектронике. В 1960-е годы Шокли увлёкся идеями евгеники и начал публичную кампанию против «вырождения» американской нации. Его расистские теории, отвергнутые обществом, разрушили научную репутацию Шокли, привели к фактическому изгнанию из научного сообщества
Несмотря на свою гениальность, он полагал, что белые американцы интеллектуально превосходят остальных, очень переживал, что «некомпетентные» люди слишком быстро плодятся и предлагал «генетически обездоленным» (то есть чернокожим) предоставлять финансовые стимулы, чтобы они соглашались на стерилизацию.
