| 英文摘要 | We theoretically study the relaxation of electron orbital states of a quantum dot due to two-phonon processes by applying a lattice relaxation approach based on a multimode description for the electron-phonon interaction. The fast relaxation time is obtained in a large energy detuning around the longitudinal optical phonon energy. This model offers an effective channel to break the phonon bottleneck. We calculate the lattice temperature and energy separation dependence of the relaxation time for different two-phonon scattering channels and obtain a good agreement with the available experimental measurement for the phonon bottleneck in quantum dots.
