In a semiconductor material, the mobilities of electrons and holes are `mu_(e)` and `mu_(h)` respectively. Which of the following is true ?

A

`mu_(e)gtmu_(n)`

B

`mu_(e)ltmu_(n)`

C

`mu_(e)=mu_(n)`

D

`mu_(e)lt0, mu_(n)gt0`

Text Solution

Verified by Experts

The correct Answer is:
A
`mu_(e) gt mu_(n)` because electron is lighter than hole.
