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.
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.
Nov 20, 2022 · Patents for transistor-like devices had been filed starting in 1925, but the first recorded instance of a working transistor was the legendary point-contact device built at AT&T Bell Telephone Laboratories in the fall of 1947.
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.
Dec 13, 2022 · The first transistor was a sort of crude metal spring pushing what looks like an arrowhead wrapped in gold foil down into a shard of germanium, the semiconductor, with all of that on top of a...
