2.Energy relaxation: the photogenerated electron and hole from the excitation process are in general in excited states in the conduction and valence bands. They go through various energy relaxation processes such as electron-phonon interactions to relax to their respective ground states, namely, the conduction- and valence-bandedge states.

3.Radiative recombination: the energy-relaxed electron and hole recombine, namely, the electron at the conduction-bandedge state transits to the empty valence-bandedge state, radiatively emits a photon with an energy . This is the same spontaneous emission studied in Sect. 2.​3.
