Question

A hole in a P-type semiconductor is
(a) An excess electron
(b) A missing electron
(c) A missing atom(d) A donor level

Answer 1

Option (B) is the right answer

Answer 2

Answer:

A hole in a P-type semiconductor is (b) a missing electron.

Explanation:

In the case of P-type semiconductors, the number of holes is greater than the number of electrons and thereby the holes form the major carriers whereas the electrons form the minor carriers.

When a trivalent impurity is added to a pure semiconductor, it results in the formation of a p-type semiconductor or extrinsic semiconductor.
