Could You describe me what it is phonon replica.
Re: Photon replica
I also need the answer for this question.
From my reading, I think the phonon replica is an interaction between exciton and lattice vibrational. Due to phonon optical energy, it helps electron-hole to recombine and emit a light. This can be observed in PL exp at high T.
Can somebody explain further about this topic pls.
*sorry for my english.
