The first transistor was successfully demonstrated on December 23, 1947, at Bell Laboratories in Murray Hill, New Jersey. Bell Labs was the research arm of American Telephone and Telegraph (AT&T). The three individuals credited with the invention of the transistor were William Shockley, John Bardeen and Walter Brattain. The introduction of the ...
A replica of the first working transistor, a point-contact transistor invented in 1947 Herbert Mataré (pictured in 1950) independently invented a point-contact transistor in June 1948. A Philco surface-barrier transistor developed and produced in 1953
A stylized replica of the point-contact transistor invented at Bell Labs on December 23, 1947. The point-contact transistor was the first type of transistor to be successfully demonstrated. It was developed by research scientists John Bardeen and Walter Brattain at Bell Laboratories in December 1947.
[30]: 153 [31]: 145 Shive's invention sparked [32] Shockley's invention of the junction transistor. [30]: 143 A few months later he invented an entirely new, considerably more robust, type of transistor with a layer or 'sandwich' structure. This structure went on to be used for the vast majority of all transistors into the 1960s, and evolved ...
The first transistor hi-fi system was developed by engineers at GE and demonstrated at the University of Philadelphia in 1955. [9] In terms of commercial production, The Fisher TR-1 was the first "all transistor" preamplifier, which became available mid-1956. [10] In 1961, a company named Transis-tronics released a solid-state amplifier, the ...
William Shockley then invented the bipolar junction transistor at BTL in 1948. [23] While early junction transistors were relatively bulky devices that were difficult to manufacture on a mass-production basis, [24] they opened the door for more compact devices. [25] Robert Noyce invented the monolithic integrated circuit chip (1959).
The invention of the transistor in December 1947 is one of the hallmark moments in humanity’s technological history, right up there with Maxwell’s equations and Alessandro Volta’s battery.
Walter Houser Brattain (/ ˈ b r æ t ən /; February 10, 1902 – October 13, 1987) was an American physicist who shared the 1956 Nobel Prize in Physics with John Bardeen and William Shockley for their invention of the point-contact transistor. [1]
