Question

From the above equation, assuming the same values for the for ni, n= p and T. Given that p0=10^5cm^-3. Calculate the quasi-fermi energy level in eV?

(a) 0.1985

(b) 0.15

(c) 0.1792

(d) 0.1

The question was asked in an interview.

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

Answer 1

Correct choice is (c) 0.1792

Explanation: Using the same equation,

 

Substituting the respective values,

EFi – EFp=0.1792 eV.
