Research topic: transistor

transistor three-terminal, solid-state electronic device used for amplification and switching. It is the solid-state analog to the triode electron tube ; the transistor has replaced the electron tube for virtually all common applications. Types of Transistors The transistor is an arrangement of semiconductor materials that share common physical boundaries. Materials most commonly used are silicon, gallium-arsenide, and germanium, into which impurities have been introduced by a process called "doping." In n -type semiconductors the impurities or dopants result in an excess... Read more
