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.

Answer :

The electrons in the conduction band are able to absorb energy from applied electric fields, thus the electrons after absorbing energy move from lower energy level to higher level in the conduction band.


Now the holes in the valence band move from higher energy level to higher energy level, towards the electric field where they will have higher energy.
