The dimensional formula for hole mobility in a semiconductor is :

A

`[M^(-1)L^(0)T^(2)A]`

B

`[M^(-1)L^(2)T^(-2)A]`

C

`[M^(0)L^(0)T^(0)A]`

D

`[ML^(-2)T^(-2)A]`

Text Solution

Verified by Experts

The correct Answer is:
A
`[mu_(h)]=("drift velocityv")/("electric field E")=([LT^(-1)][AT])/([MLT^(-2)])=[M^(-1)T^(2)A].`
Hence `(a)` is the correct choice.
