Question

If excess charge carriers are created in the semiconductor then the new Fermi level is known as Quasi-Fermi level. Is it true?

(a) True

(b) False

This question was posed to me in exam.

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

Answer 1

Correct answer is (a) True

Easiest explanation: Quasi-fermi level is defined as the change in the level of the Fermi level when the excess chare carriers are added to the semiconductor.
