Question

Distinguish between p-type and n-type semiconductors.

✓

Answer

p-typed
(i) Number of holes are more than the number of electrons
(ii) Trivalent impurities are used for doping
(iii) These are called as acceptors
(iv) Holes are majority charge carriers.

n-typed
(i) Number of electrons are more than the number of holes.
(ii) Pentavalent impurities are used for doping.
(iii) These are called as doners
(iv) Electrons are majority charge carriers
