| 中文摘要 | we have investigated the evolution of exciton state filling in inas/gaas quantum dot (qd) structures as a function of the excitation power density by using rnicro-photoluminescence spectroscopy at different temperatures. in addition to the emission bands of exciton recombination corresponding to the atom-like s, p and d, etc. shells of qds, it was observed that some extra states v between the s and p shells, and d' between the p and d shells appear in the spectra with increasing number of excitons occupying the qds at a certain temperature. the emergence of these inter-shell excitonic levels is power density and temperature dependent, which is an experimental demonstration of strong exciton-exciton exchange interaction, state hybridization, and coupling of a multi-exciton system in qds.
