Which of the following expression represent the correct formulae for calculating the exact position of the Fermi level for p-type material?
(a) EF = EV + kTln(ND / NA )
(b) EF = -EV + kTln(ND / NA )
(c) EF = EV – kTln(ND / NA )
(d) EF = -EV – kTln(ND / NA )
The question was posed to me in an interview.
I want to ask this question from Fermi Level in a Semiconductor having Impurities topic in portion Conduction in Semiconductors of Electronic Devices & Circuits
