When the semiconductor is heated ……..

A

the number of electrons increases, while the number of holes decreases.

B

the number of holes increases, while the number of electron decreases.

C

the number of electrons and holes remains the same.

D

the number and electrons and holes increases equally.

Text Solution

Verified by Experts

The correct Answer is:
D
the number and electrons and holes increases equally.
Heating the semiconductor breaks down their covalent bonds, producing as many holes as the electrons release.
