The  fF (E) decreases in which of the following band for p-type semiconductor?

(a) Conduction band

(b) Donor band

(c) Acceptor band

(d) Valence band

This question was posed to me in an interview.

This intriguing question originated from Charge Densities in a Semiconductor impurities topic in chapter Conduction in Semiconductors of Electronic Devices & Circuits

Best answer
Correct choice is (a) Conduction band

Easiest explanation: The probability of finding the electron in the conduction band decreases for a p-type semiconductor because in a p-type semiconductor, the holes will be in conduction band rather than the electrons.
