Question

Write two characteristic features to distinguish between n-type and p-type semiconductors.

Answer 1

N- type semiconductor is an extrinsic semiconductor which is obtained by doping the impurity atoms, such as antimony, phosphorus, arsenic, etc. to pure germanium or silicon semiconductor.
The electrons are the majority charge carriers and holes are minority charge carriers.

P - type semiconductor is an extrinsic semiconductors which is obtained by doping trivalent impurities of atoms, such as boron, gallium, indium, etc. to the pure germanium or silicon semiconductor.
The holes are majority charge carriers and elections are minority charge carriers.
