Question
An n-type semiconductor has electron density of 10^14 cm-3. It is exposed to a light source which causes 10^13 electron-hole pairs per cm^-3 being created
An n-type semiconductor has electron density of 10^14 cm-3. It is exposed to a light source which causes 10^13 electron-hole pairs per cm^-3 being created every microsecond. Assume 2 μs lifetime for holes and electrons and intrinsic carrier concentration of 10^10 cm^-3, find the minority carrier density at the moment when the light is being turned OFF.
