SRH and radiative recombination

  1. Oct 15, 2011 #1

    I have read in different references that trap assisted SRH recombination is non radiative and gives the energy to phonons.

    However, I have not been able to understand why is not possible to generate photons in this case. I mean, can SRH recombination give the energy to photons? What determines in this case if photons or phonons are emmited?

    Thanks for any help.

    Any idea?

    I have the same question!

    I seem to remember that GaP doped with N can emit green light, is this an example giving the energy to photons?
