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

`mu_(e) gt mu_(h)`

`mu_(e) lt mu_(h)`

`mu_(e) = mu_(h)`

`mu_(e) lt 0` , `mu_(h)gt0`

Text Solution

Verified by Experts

The correct Answer is:

`mu_(e) gt mu_(h)`, as `mu=(etau)/(m)`.
Since electron require smaller energy for moving through crystal lattice.
