n-type semiconductors:-
1. when pentavalent impurity atoms as, sb etc. added in intrinsic semiconductor, n-type semiconductor.
2. majority carriers in n-type semiconductor electrons , minority carries holes.

p-type semiconductors:-
1. when trivalent impurity atoms gallium, indium etc. added in intrinsic semiconductor, p-type semiconductor.
2. majority carriers in p-type semiconductor holes , minority carriers electrons.
