A) Decreases exponentially with increasing band gap
B) Increases exponentially with increasing band gap
C) Decreases with increasing temperature
D) Is independent of the temperature and the band gap
Correct Answer: A
Solution :
The probability of electrons to be found in the conduction band of an intrinsic semiconductor \[P(E)=\frac{1}{1+{{e}^{\frac{(E-{{E}_{F}})}{kT}}}}\]; where k = Boltzmann's constant Hence, at a finite temperature, the probability decreases exponentially with increasing band gap.You need to login to perform this action.
