    What Is Transistor ? A transistor is a semiconductor device used

    to amplify and switch electronic signalsand electrical power . It is composedof semiconductor material with at least threeterminals for connection to an external circuit. Avoltage or current applied to one pair of thetransistor's terminals changes the currentthrough another pair of terminals. Because thecontrolled (output) power can be higher than thecontrolling (input) power, a transistorcan amplify a signal. Today, some transistors arepackaged individually, but many more are foundembedded in integrated circuits .

    The transistor is the fundamental buildingblock of modern electronic devices , and is ubiquitousin modern electronic systems. Following itsdevelopment in 1947 by American physicists JohnBardeen , Walter Brattain , and William Shockley , thetransistor revolutionized the field of electronics,and paved the way for smaller andcheaper radios , calculators , and computers , amongother things. The transistor is on the list of IEEE milestones in electronics, and the inventors were

    jointly awarded the 1956 Nobel Prize in Physics fortheir achievement.

    HistoryBefore Transistors Were Invented, Circuits Used Vacuum Tubes:

    Fragile, Large In Size, Heavy, Generate Large Quantities Of Heat, Require A Large Amount Of

    PowerThe First Transistors Were Created At Bell Telephone Laboratories In 1947

    William Shockley, John Bardeen, And Walter Brattain Created The Transistors In And Effort To

    Develop A Technology That Would Overcome The Problems Of Tubes

    The First Patents For The Principle Of A Field Effect Transistor Were Registered In 1928 By

    Julius Lillenfield.

    Shockley, Bardeen, And Brattain Had Referenced This Material In Their Work

    The Word Transistor Is A Combination Of The Terms Transconductance And Variable

    Today An Advanced Microprossesor Can Have As Many As 1.7 Billion Transistors.

    William Shockley William Bradford Shockley Jr. (February 13, 1910 August 12, 1989)Was An American Physicist And Inventor . Shockley Was The ManagerOf A Research Group That Included John Bardeen And Walter Houser

    Brattain , The Duo Which Invented The Transistor . For This Feat, AllThree Were Awarded The 1956 Nobel Prize In Physics.

    Shockley's Attempts To Commercialize A New TransistorDesign In The 1950s And 1960s Led To California's " SiliconValley" Becoming A Hotbed Of Electronics Innovation. In HisLater Life, Shockley Was A Professor At Stanford And BecameA Staunch Advocate Of Eugenics.

    John Bardeen John Bardeen (May 23, 1908 January 30, 1991) was anAmerican physicist and electrical engineer , the only person to have wonthe Nobel Prize in Physics twice: first in 1956 with WilliamShockley and Walter Brattain for the invention of the transistor ; and againin 1972 with Leon N Cooper and John Robert Schrieffer for a fundamentaltheory of conventional superconductivity known as the BCS theory .The transistor revolutionized the electronics industry, allowingthe Information Age to occur, and made possible the development of almostevery modern electronic device, from telephones to computers to missiles.Bardeen's developments in superconductivity, which won him his secondNobel, are used in Nuclear Magnetic Resonance Spectroscopy (NMR) or itsmedical sub-tool magnetic resonance imaging (MRI).In 1990, John Bardeen appeared on LIFE Magazine ' s list of "100 MostInfluential Americans of the Century
