Question

When the temperature of either n-type or p-type increases, determine the movement of the position of the Fermi energy level?

(a) Towards up of energy gap

(b) Towards down of energy gap

(c) Towards centre of energy gap

(d) Towards out of page

This question was addressed to me at a job interview.

Asked question is from Fermi Level in a Semiconductor having Impurities topic in section Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

The correct option is (c) Towards centre of energy gap

The explanation: whenever the temperature increases, the Fermi energy level tends to move at the centre of the energy gap.
