Free electrons and holes

Vedclass · Answer

(B) In a semiconductor,the charge carriers responsible for the flow of electric current are both free electrons (in the conduction band) and holes (in the valence band).When an external electric field is applied,these charge carriers undergo drift,resulting in an electric current.Therefore,the current in a semiconductor is due to the drift of both free electrons and holes.

Through a semiconductor,an electric current is due to the drift of
