Question

what is a hole. what type of doping creates a hole?​

Answer 1

Answer:

A hole is an absence of an electron in a particular place in an atom. It is an electric charge carrier with a positive charge, equal in magnitude but opposite in polarity to charge on the electron. Although it is not a physical particle, it can be passed from atom to atom in a semiconductor material.

Holes are created when a pure semiconductor is doped with a trivalent impurity i.e. p-type semiconductor is formed.
