A transistor is basically a Si on Ge crystal containing three separate regions. It can be either NPN or PNP type fig. 1. The middle region is called the base and the outer two regions are called emitter and the collector. The outer layers although they are of same type but their functions cannot be changed. They have different physical and electrical properties.
