In the energy band diagram of a material shown below, the open circles and filled circles denote holes and electrons respectively. The material is:-

A

p-type semiconductor

B

insulator

C

metal

D

n-type semiconductor

Text Solution

Verified by Experts

The correct Answer is:
A

In the given situation the number of holes velence band is greater than number of electrons in conduction band. So it is p-type semiconductor.
