The transistor acts like an insulator or a switch that is turned off. When a positive voltage is applied to the base, electrons are pulled out of the junctions and they no longer act as barriers.

These are analogous to the terminals on a bipolar transistor, in that the source fulfills a similar role to the emitter, the gate to the base, and the drain to the collector. Thus the three basic ...

Electricity can race through. The transistor base (the "meat" of the sandwich) acts like the handle on a faucet. Turn it one way and current will gush through like water through a hose.

A slight surprise comes in how point contact transistors are used, unlike today’s devices their gain in common emitter mode was so poor that they took instead a common base configuration.

This new transistor is composed of two coupled graphene/germanium Schottky junctions. During operation, germanium injects ...
