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

A

`mu_(h)gtmu_(e)`

B

`mu_(e)gtmu_(h)`

C

`mu_(e)=mu_(h)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

Effective mass of holes are greater than the mass of electron so mobility of electron is more as compared to holes.
`mu_(e)gtmu_(h)`
