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 ...
Herbert Franz Mataré (22 September 1912 – 2 September 2011 [1]) was a German physicist.The focus of his research was the field of semiconductor research. His best-known work is the first functional European transistor, which he developed and patented together with Heinrich Welker in the vicinity of Paris in 1948, independent from the Bell Labs engineers who had developed the first ...
The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p ...
Its roots can be traced to the invention of the transistor by Shockley, Brattain, and Bardeen at Bell Labs in 1948. [1] [2] Bell Labs licensed the technology for $25,000, [3] and soon many companies, including Motorola (1952), [4] Schockley Semiconductor (1955), Sylvania, Centralab, Fairchild Semiconductor and Texas Instruments were making ...
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.
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.
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 ...
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]
