Which outcome increases sharply within a quantum dot when exceeding the exciton binding energy?

💡 Explanation

Phonon-assisted energy relaxation rate enhances as a process, because above the exciton binding strength, electrons rapidly dissipate using vibrational lattice through electron-phonon interactions, therefore energy relaxation increases markedly above this energy, rather than other recombinations.
