Question

The thermal equilibrium concentration of the electrons in the conduction band and the holes in the valence band depends upon?

(a) Effective density of states

(b) Fermi energy level

(c) Both A and B

(d) Neither A nor B

I had been asked this question by my school teacher while I was bunking the class.

Asked question is from Electrons and Holes in Semiconductor topic in portion Conduction in Semiconductors of Electronic Devices & Circuits

Answer 1

Right choice is (c) Both A and B

To explain: The electrons and holes depends upon the effective density of the states and the Fermi energy level given by the formula,
