Module 6 : PHYSICS OF SEMICONDUCTOR DEVICES
Lecture 34 : p- type Semiconductors
In the band picture, the acceptor energy level $ E_a$ lies close to the top of the valence band. Electrons near the top of the valence band can be thermally excited to the acceptor level leaving holes near the top of the valence band. In these semiconductors, known as P-type semiconductors, the primary current is due to majority carriers which are holes.
