Consider a p-type semiconductor that has a band gap of 1.0 eV and a minority electron lifetime of 0.1 µs, and is uniformly illuminated by light having photon energy of 2.0 eV.
What rate of uniform excess carrier generation is required to generate a uniform electron concentration of 1010/cm3?
How much optical power per cm3 must be absorbed in order to create the excess carrier population of part (a)? (You may leave your answer in units of eV/s-cm3.)
If the carriers recombine via photon emission, approximately how much optical power per cm3 will be generated? (You may leave your answer in units of eV/s-cm3.)
What do we mean by “deep” versus “shallow” traps? Which are more harmful for semiconductor devices ...
