Like for the absorption, a direct-gap semiconductor emits light only at the resonances corresponding to the s -like states. As a typical trend, a quasiequilibrium emission is strongly peaked around the 1 s resonance because S λ λ is usually largest for the λ λ = 1 s ground state. This emission peak often remains well below the fundamental bandgap energy even at the high excitations where all states are continuum states. This demonstrates that semiconductors are often subjects to massive Coulomb-induced renormalizations even when the system appears to have only electron–hole plasma states as emission resonances. To make an accurate prediction of the exact position and shape at elevated carrier densities, one must resort to the full SLEs.
