Answer to Question #181053 in Physics for Hoang Minh Quan

Question

A direct recombination semiconductor sample has Na-Nd= 10¹⁶ cm^-3 and T=Tn=Tp= 1×10^-6 s. It is illuminated until a uniform excess minority density of 10⁶ cm^-3 has been generated. The light is turned off at t=0.

1/ What is the recombinarion rate immediately after the light is turned off for the excess minority carrier ?

2/ What is this rate for the excess majority carrier?
