The electrical conductivity of pure silicon can be increased by

A

increasing the temperature

B

doping donor impurities

C

doping acceptor impurities

D

falling ultraviolet light on it

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
The electrical conductivity of pure silicon can be increased by increasing the number of current carriers. Which can be done by incresing the temperature, or by doping donor impurities, or acceptor impurities, or by falling ultraviolet light on it.
