Consider a semiconductor that is uniformly doped with N = 10¹4 cm³ and N₁ = 0, with an applied electric field of E = 100 V/cm. Assume that μ = 1000 cm²/V-s and μp = 0. Also assume the following parameters: N = 2 x 10¹ (T/300)³/² cm-³ N. = 1 × 10¹⁹ (T/300)³/2² cm-³ 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.)
