3. (10 points) Consider the GaAs crystal at 200 K. a) Calculate the intrinsic conductivity at this temperature. Use the facts that the intrinsic concentration of electrons is n;= 2.1 x 106 cm3 at 300 K, electron and hole mobilities are Me 8500 cm² V-1 s-and un = 400 cm² V-1 s:!, and the energy gap is 1.42eV. 3
