The probability of electrons to be found in the conduction band of an intrinsic semiconductor at a finite temperatureA. increases expon entially with increasing band gapB. decreases exponentially with increasing band gapC. decreases with increasing temperatureD. is independent of the temperature and the band gap

Answer» Correct Answer - B
`N = N_0e^(-E_g//K_BT` where `E_g` is the band gap. At a finite temperature, the probability of jumping of an electron from the valence band to the conduction band decreases exponentially with increasing band gap.
