中文摘要	we have investigated the evolution of exciton state filling as a function of excitation power density in inas/gaas quantum dots (qds). in addition to the emission bands of exciton recombination corresponding to the atom-like s, p, and d, etc. shells of quantum dots, it was observed that some extra states, p-' (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. the emergence of these intershell excitonic levels is an experimental demonstration of strong exciton-exciton exchange interaction and coupling as well as state mixing and hybridization of a multiexciton system in quantum dots.
