Leopoldo B. Valdes
Leopoldo Benjamin Valdes was a pioneer in semiconductors. He was one of the first four recruits by William Shockley to help develop technologies at Shockley Semiconductor Laboratory. Career During the winter of 1954–1955, William Shockley decided to seek a sponsor to help him establish production of complex transistors and his own Shockley diodes. He was initially supported by Raytheon Company, Raytheon, but the agreement was soon canceled by that company. After Shockley subsequently established Shockley Semiconductor Laboratory under the umbrella of Beckman Instruments, he recruited William W. Happ who he knew from Raytheon. Shockley's other three initial recruits were George Smoot Horsley and Valdes both of whom he knew from Bell Labs, and Richard Victor Jones, who was then a new University of California, Berkeley, Berkeley graduate. Valdes, as the most experienced of the group, was tasked with setting up crystal growing equipment. He also brought lists of equipment suppliers ...

Silicon Valley People
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepare it and characterize it in pure form. Its oxides form a family of anions known as silicates. Its melting and boiling points of 1414 °C and 3265 °C, respectively, are the second highest among all the metalloids and nonmetals, being surpassed only by boron. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth's crust. It is widely distributed in space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide (s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Smoot Horsley
George Smoot Horsley (1916 – 1992) was a physicist and pioneer in printed circuitry and semiconductors. He was one of the first four recruits by William Shockley to help develop technologies at Shockley Semiconductor Laboratory. Early life Horsley was born in 1916 in Brigham City, Utah to Mormon parents Golden and Mary Horsley. He served in the US Army Air Corps during World War II, originally commissioned a Second Lieutenant in 1942 and assigned to field artillery. He attained the rank of First Lieutenant and earned his Aviator Badge to become a pilot in October 1943. He had served as a missionary and in 1945 was named an acting Chaplain aboard a ship bound for North Africa. He served in Africa and Italy. In 1945, near the close of the war, he began taking a course in Algebra with the Armed Forces Institute.

Shockley Diode
The Shockley diode (named after physicist William Shockley) is a four-layer semiconductor diode, which were one of the first semiconductor devices invented. It is a PNPN diode, with alternating layers of P-type and N-type material. It is equivalent to a thyristor with a disconnected gate. Shockley diodes were manufactured and marketed by Shockley Semiconductor Laboratory in the late 1950s. The Shockley diode has a negative resistance characteristic. It was largely superseded by the diac. Working Unlike other semiconductor diodes, the Shockley diode has more than one PN junction. The construction includes four sections of semiconductors placed alternately between the anode and cathode in the pattern of PNPN. Though it has multiple junctions, it is termed a diode for being a two-terminal device. The Shockley diode remains in an OFF state, with a very high resistance, until a voltage greater than the trigger voltage is applied across its terminals. When the voltage exceeds th ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

William Shockley
William Bradford Shockley Jr. (February 13, 1910 – August 12, 1989) was an American physicist and inventor. He was the manager of a research group at Bell Labs that included John Bardeen and Walter Brattain. The three scientists were jointly awarded the 1956 Nobel Prize in Physics for "their researches on semiconductors and their discovery of the transistor effect". Partly as a result of Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s, California's Silicon Valley became a hotbed of electronics innovation. In his later life, while a professor of electrical engineering at Stanford University and afterward, Shockley became widely known for his racist views and advocacy of eugenics. Early life and education Shockley was born to American parents in London on February 13, 1910, and was raised in his family's hometown of Palo Alto, California, from the age of three. His father, William Hillman Shockley, was a mining engineer who speculated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
