中文摘要	deep-level transient spectroscopy and photoluminescence studies have been carried out on structures containing self-assembled inas quantum dots formed in gaas matrices. the use of n- and p-type gaas matrices allows us to study separately electron and hole levels in the quantum dots by the deep-level transient spectroscopy technique. from analysis of deep-level transient spectroscopy measurements it follows that the quantum dots have electron levels 130 mev below the bottom of the gaas conduction band and heavy-hole levels at 90 mev above the top of the gaas valence band. combining with the photoluminescence results, the band structures of inas and gaas have been determined.
