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 ...
The original transistor is still proudly featured behind a glass encasement in the lobby of the Nokia Bell Labs campus in Murray Hill. The world’s first working solid-state amplifier spawned several industries, and that small slab of germanium introduced the power of semiconductors.
Jun 21, 2024 · The first transistor, invented by American physicists John Bardeen, Walter H. Brattain, and William B. Shockley. (more) Bardeen’s conjecture spurred a basic research program at Bell Labs into the behaviour of these “surface-state” electrons.
First transistor (replica), Bell Labs, 1947. The first transistor used two closely spaced gold contacts pressed onto the surface of a slab of high-purity germanium.
Jun 14, 2024 · The Transistor, 1947: Bell Labs’ John Bardeen, Walter Brattain, and William Shockley invent the transistor, replacing vacuum tubes and mechanical relays and revolutionizing the entire electronics world. The team was awarded a Nobel Prize in 1956.
Dec 23, 2009 · Bell Labs publicly announced the first transistor at a press conference in New York on June 30, 1948. The transistor went on to replace bulky vacuum tubes and mechanical relays.
On December 16, 1947, their research culminated in the first successful semiconductor amplifier. Bardeen and Brattain applied two closely-spaced gold contacts held in place by a plastic wedge to the surface of a small slab of high-purity germanium.
