Question

How can a p-type semiconductor be created by doping silicon?

Answer 1

p-Type Semiconductor:

p-type semiconductors are extrinsic semiconductors having trivalent impurity.

Explanation:

1. Trivalent atoms like Aluminum and Boron added to an intrinsic semiconductor like Silicon, Germanium makes it a p-type semiconductor.
2. Adding impurity to a pure or intrinsic semiconductor is known as doping.
3. Hence, silicon, an intrinsic semiconductor doped with a trivalent impurity, makes it a p-type semiconductor.
