Number of electrons present in conduction band due to doping

Question

Number of electrons present in conduction band due to doping (A) shows a heavy increase with increase of temperature (B) shows a heavy decrease with increase of temperature (C) independent of change in ambient temperature (D) reduces to zero at temperature above room temperature

Tardigrade Admin · Accepted Answer

The number of electrons made available for conduction by dopant atoms depends strongly upon the doping level and is independent of any increase in ambient temperature.

Q. Number of electrons present in conduction band due to doping

shows a heavy increase with increase of temperature

shows a heavy decrease with increase of temperature

independent of change in ambient temperature

reduces to zero at temperature above room temperature
