Text Solution

Verified by Experts

Semiconductor : A meterial whose electrical conductivity is of the order of `10^(-9) - 10^(2) ohm^(-1) cm^(-1)` is called a semiconductor. It allows flow of current only in one direction.
There are two types of semiconductors :
(i) p-type semiconductor, (ii) n-type semiconductor.
