when the electrical conductivity of a semiconductor is due to the breaking of its covalent bonds, then the semiconductor is said to be

A

Donor

B

Acceptor

C

Intrinsic

D

Extrinsic

Text Solution

Verified by Experts

The correct Answer is:
C
In intrinsic semiconductor, conductivity is due to the breaking of covalent bond.
In Extrinsic semiconductor, conductivity is due to the breaking of covalent bond and excess of charge carriers are mainly due to impurity.
