Q.No.222: - Describe the
motion of electron and holes in a semiconductor.
Ans: - In a semiconductor the
current flows due to the motion of electrons and shifting of holes. The
electrons occupy the place of holes and made a hole in their own place and the
upcoming electron take the place of that hole and so on. So in semiconductors
the current due to electrons flow in one direction and the current due to
shifting of holes flow in other direction.
