Polarons in semiconductor quantum-dots and their role in the quantum kinetics of carrier relaxation
arXiv:cond-mat/0406563 · doi:10.1103/PhysRevB.71.125327
Abstract
While time-dependent perturbation theory shows inefficient carrier-phonon scattering in semiconductor quantum dots, we demonstrate that a quantum kinetic description of carrier-phonon interaction predicts fast carrier capture and relaxation. The considered processes do not fulfill energy conservation in terms of free-carrier energies because polar coupling of localized quantum-dot states strongly modifies this picture.
