Semiconductors: Basic Structures

These pages provide an overview of basic semiconductor construction and behavior.

Basic Semiconductor Crystal Structure: Every semiconductor design starts with a single crystal of pure material, either silicon or germanium. Then we make some changes to it...
The PN Junction: A single type of semiconductor material won't do much by itself, beyond acting as a resistance. But when we put them together, useful things begin to happen.
The Transistor: Extending the crystal to have two junctions increases its usefulness greatly.
The Early Effect: That three-layer device is nice, but does exhibit a problem...
