Question

The effect of increase in temperature on the number of electrons in conduction band ( n e ) and resistance of a semiconductor will be as: (A) n e decreases, resistance increases (B) Both n e and resistance increase (C) n e increases, resistance decreases (D) Both ne and resistance decrease

Tardigrade Admin · Accepted Answer

As temperature increases, more electron excite to conduction band and hence conductivity increases, therefore resistance decreases.

Q. The effect of increase in temperature on the number of electrons in conduction band $(n_{e})$ and resistance of a semiconductor will be as:

$n_{e}$ decreases, resistance increases

Both $n_{e}$ and resistance increase

$n_{e}$ increases, resistance decreases

Both $n_{e}$ and resistance decrease

As temperature increases, more electron excite to conduction band and hence conductivity increases, therefore resistance decreases.

Q. The effect of increase in temperature on the number of electrons in conduction band (ne​) and resistance of a semiconductor will be as:

ne​ decreases, resistance increases

Both ne​ and resistance increase

ne​ increases, resistance decreases

Both ne​ and resistance decrease

As temperature increases, more electron excite to conduction band and hence conductivity increases, therefore resistance decreases.
