A semiconductor in thermal equilibrium has a hole, Ask an Expert

Engineering

A semiconductor, in thermal equilibrium, has a hole concentration of p0 = 2x1016 cm-3. The minority carrier life time = 3x10-7 s. (Assume, ni = 1010 cm-3)

(a) Determine the thermal equilibrium recombination rate of electrons
(b) Determine the recombination rate of electrons if an excess electron concentration of ?n = 1013 cm-3 exists.
(c) Calculate the change in the recombination rate when excess electron concentration exists (compared to thermal equilibrium).
