When an electric field is applied across a semiconductor,

A

electrons move from lower energy level to higher energy level in the conduction band.

B

electrons move from higher energy level to lower energy level in the conduction band.

C

holes in the valence band move from higher energy level to lower energy level.

D

holes in the valence band move from lower energy level to higher energy level.

Text Solution

Verified by Experts

The correct Answer is:
A, C
Electrons in conduction band get accelerated and acquire energy by the application of electric field and move from lower energy level to higher energy level.
While holes in valence band move from higher energy level to lower energy level.
