ZnO is considered a wide band gap semiconductor (Eg=3.2eV). Assume that the effective mass for electrons and holes are .25mo, where mo is the rest mass of a free electron. Consider that for your ZnO crystal the mobility of the free carriers is 100cm?/V-sec. If you dope the crystal with donors with a density of 1015 cm?, calculate the conductivity of the material at room temperature if the energy position of the impurities is 0.2eV below the conduction band edge.
