Let `n_(p)` and `n_(e)` be the number of holes and conduction electrons respectively in a semiconductor. Then

A

`n_(p)gtn_(e)` in an intrinsic semiconductor

B

`n_(p)=n_(e)` in an extrinsic semiconductor

C

`n_(p)=n_(e)` in an intrinsic semiconductor

D

`n_(e)gtn_(p)` in an intrinsic semiconductor

Text Solution

Verified by Experts

The correct Answer is:
C
In intrinsic semiconductors, the creation or liberation of one free electron by the thermal energy has created one hole. Thus in intrinsic semiconductors `n_(e)=n_(h)`
