1014 cm3, p450 cm2/V s and minority carrier lifetime T, 1 us is uniformly illuminated by a photon flux G = 1018 Assume that a n-type region of crystalline silicon with Np 1. /cm2s and reaches a steady state. It is then switched off at t 0. Write down the simplest form of the minority carrier diffusion equation that accurately describes its behavior. Briefly justify your answer Solve for and sketch the time-dependent decay of the minority carrier concentration from t 0 to t 10 us a. b. What are the values of the minority carrier concentration at t 1 us and t= 5 us c. respectively?
