Consider an n-type semiconductor at t 300 k in thermal equilibrium (no current). assume that the donor concentration varies as nd(x) nd0exl over the range 0 x l where nd0 1016 cm3 and l 10 m. (a) determine the electric fi eld as a function of x for 0 x l. (b) calculate the potential difference between x 0 and x l (with the potential at x 0 being positive with respect to that at x
