Define electron motion in a semiconductor.

Text Solution

Verified by Experts

To move the hole in a given direction, the valence electrons move in the opposite direction. Electron flow in an N-type semiconductor is similar to electrons moving in a metallic wire.The N-type dopant atoms will yield electron available for conduction.
