Q.No.216: - What are the p-type and n-type semi-conductors?

Ans: - The intrinsic semi-conductors which are doped with pentavalent impurity atom becomes an n-type semiconductor because of majority of electrons and the intrinsic semiconductors which are doped with trivalent impurity atom becomes a p-type semiconductor because of the majority of positively charged holes.
