Question

Electric current produced in semiconductor is due to movement of

Answer 1

The carrier particles, namely the holes and electrons of a semiconductor, move from a place of higher concentration to a place of lower concentration. Hence, due to the flow of holes and electrons there is a current. ... Due to this gradient, an electric field is produced in the semiconductor.

Answer 2

In a semiconductor, current is produced in two different ways. There are the electron current and the hole current. The electron current is produced when electrons are pushed from the negative terminal into the semiconductor. Holes are positions in the semiconductor atoms that can be but are not occupied by electrons.
