Question

Which has higher mobility, electron or hole ?

Answer 1

The electron mobilty is oftengreater than hole mobilitybecause quite often, the electroneffective mass is smaller thanhole effective mass. The relaxation times are often of the same order of magnitude forelectrons and holes and therefore, they do not make too much difference.

Answer 2

The electron mobilty is often greater than hole mobility because quite often, the electron effective mass is smaller than hole effective mass. The relaxation times are often of the same order of magnitude for electrons and holes and therefore, they do not make too much difference.
