1. The following data is available for an undoped semiconductor: n, 1010 /cc, T= 300 K, N. = 3 x 10" /cc , and Ny = 2.5 x 10" /cc, me =9.1 x 10-32 Kg. Determine: (a) The effective mass of the holes in the valance band, (b) the energy gap of the semiconductor, (c) the Fermi level relative to the conduction band in eV. (d) the thermal velocity of holes.
