In a semiconductor consider the energy level lying 0.11 eV below Fermi level. Find: (a) The probability of this level being occupied by the electron at room temperature. (b) The probability of this level not being occupied by the electron at room temperature. (c) The probability of this level not being occupied by the electron at 500 K. (d) Discuss your result! high there is 1 % probability that the state with energy 0.5 eV
