What exactly is a transistor, anyway? | HowStuffWorks

To create transistors, engineers layered doped germanium to make two layers back to back, in a configuration of either P-N-P or N-P-N The point of contact was called a junction, thus the name junction transistor With an electrical current applied to the center layer (called the base), electrons will move from the N-type side to the P-type side...
