The probability of electrons to be found in the conduction band of an intrinsic semiconductor at finite temperature is which of the following?
(a) Increases exponentially with the increasing bandgap
(b) Decreases exponentially with the increasing bandgap
(c) Decreases with increasing temperature
(d) Is independent of the temperature and the bandgap
I had been asked this question during an internship interview.
