Question

Write the differences between n-type and p-type semiconductors.

Answer 1

n-type	p-type
1) Majority charge carriers are electrons. 2) Minority charge carriers are holes. 3) Produced by adding pentavalent impurities 4) Electrical conductivity is mainly due to free electrons. Ex: Ge doped with Arsenic	1) Majority charge carriers are holes. 2) Minority charge carriers are electrons. 3) They are produced by adding trivalent impurities 4) Electrical conductivity is mainly due to holes. Ex: Ge doped with Indium
