Field Effect ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The Transistor is Born Brattain & Gibney observe field effect in silicon sample; amplified effect when electrolytes are used Bardeen suggests n-type germanium; discover method to raise minority carrier population in n-layer Increase frequency response by allowing direct metal-semiconductor slab contact, eliminating “gu”. Now able to amplify power & voltage at a high frequency response Shockley proposes applying voltage through “gu” at the p-n junction rather than point contacts; Brattain anxious to attempt, but gets the flu and experiment is forgotten. http://nobelprize.org/educational_games/physics/transistor/function/images/bild11.gif
