Q. Doping of a semiconductor __ its electrical conductivity to a great extend

A
Increase
B
Decrease
C
Does not Change
D
None of these
Solution:

Doping of a semiconductor increase its electrical conductivity to a great extend. Therefore, as doping increases, the conductivity of a p-type semiconductor also increases (more acceptor states means more free holes that can permeate the valence band).
