John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947. Shockley introduced the improved bipolar junction transistor in 1948, which entered production in the early 1950s and led to the first widespread use of transistors.
History. Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1925. The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a substantial amount of power.
Jan 24, 2024 · The inventors of the first transistor, Shockley, Bardeen, and Brattain, were honored with the Nobel Prize in Physics, with Shockley often referred to as the father of the transistor. A copy of the first transistor.
Jan 17, 2024 · John Bardeen, Walter Brattain, and William Shockley are credited with the invention of the transistor. This transformative discovery, emerging in the mid-20th century, fundamentally altered the trajectory of technology.
His citation reads: "Theoretical physicist John Bardeen (1908–1991) shared the Nobel Prize in Physics twice—in 1956, as co-inventor of the transistor and in 1972, for the explanation of superconductivity. The transistor paved the way for all modern electronics, from computers to microchips.
Oct 11, 2019 · “The various historical records say that the transistor was invented Dec. 23, 1947 at AT&T’s Bell Laboratories by scientists William Shockley, John Bardeen, and Walter Brattain. On that...
Dec 4, 2013 · While working at Cambridge University, England in 1934, German electrical engineer and inventor Oskar Heil filed a patent on controlling current flow in a semiconductor via capacitive coupling at an electrode – essentially a field-effect transistor.
Jul 3, 2019 · The transistor was the first device designed to act as both a transmitter, converting sound waves into electronic waves, and resistor, controlling electronic current. The name transistor comes from the 'trans' of transmitter and 'sistor' of resistor.
Oct 30, 2024 · The transistor was invented in 1947–48 by three American physicists, John Bardeen, Walter H. Brattain, and William B. Shockley, at the American Telephone and Telegraph Company’s Bell Laboratories.
Nov 8, 2024 · The invention of the transistor in 1947 by John Bardeen, Walter H. Brattain, and William B. Shockley of the Bell research staff provided the first of a series of new devices with remarkable potential for expanding the utility of electronic equipment (see photograph).
