Assuming that the effective mass of electrons in the


Assuming that the effective mass of electrons in the conduction band of GaAs is temperature independent and equal to m* = 0.067mo* , determine the effective density of states Nc at T1= 77k, Tr =300k and Th=450k. Given that the density of states is tempature independent, explain the orgin of the temerture dependence of the effective density of states.
