Consider a semiconductor that is uniformly doped with N = 104 cm and N = 0, with an applied electric field of E = 100 V/cm. Assume that = 1000 cm/V-s and p = 0. Also assume the following parameters: N = 2 x 10 (T/300)/ cm- N. = 1 10 (T/300)/2 cm- E, = 1.10 eV (a) Calculate the electric-current density at T = 300 K. (b) At what temperature will this current increase by 5 percent? (Assume the mobilities are independent of temperature.)
