The introduction of the transistor is often considered one of the most important inventions in history. [1] [2] Transistors are broadly classified into two categories: bipolar junction transistor (BJT) and field-effect transistor (FET). [3] The principle of a field-effect transistor was proposed by Julius Edgar Lilienfeld in 1925. [4]
Invention year: 1947; 78 years ago () Number of terminals: 3: ... The first working device was a point-contact transistor invented in 1947 by physicists John Bardeen, ...
TRADIC. This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s.
1947: The first transistor, a bipolar point-contact transistor, is invented by John Bardeen and Walter Brattain under the supervision of William Shockley at Bell Labs. 1948: The first atomic clock is developed at the National Bureau of Standards. 1948: Basic oxygen steelmaking is developed by Robert Durrer. The majority of steel manufactured in ...
The first practical transistor was the point-contact transistor, invented by the engineers Walter Houser Brattain and John Bardeen while working for William Shockley at Bell Labs in 1947. This was a breakthrough that laid the foundations for modern technology. [2] Shockley's research team also invented the bipolar junction transistor in 1952.
John Bardeen (/ b ɑːr ˈ d iː n /; May 23, 1908 – January 30, 1991) [2] was an American mathematical physicist and electrical engineer.He is the only person to be awarded the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N. Cooper and John Robert Schrieffer for a fundamental theory of ...
The MOSFET was invented by Kahng along with his colleague Mohamed Atalla at Bell Labs in 1959. He was a researcher at Bell Telephone Laboratories in Murray Hill, New Jersey, and he invented MOSFET (metal–oxide–semiconductor field-effect transistor), which is the basic element in most of today's electronic equipment, with Mohamed Atalla in ...
The first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic ...
