Answer 1

CONCEPT:

The material which is not a good conductor or a good insulator is called as a semiconductor.
For example: Silicon
The charge carriers which are present in more quantity in a semiconductor compared to other particles are called the majority charge carrier.

There are two types of semiconductors:

P-type semiconductor:

The semiconductor having holes as majority charge carriers and electrons as a minority charge carrier is called a P-type semiconductor.

N-type semiconductor:

The semiconductor having electrons as majority charge carriers and holes as a minority charge carrier are called N-type semiconductor.
