英文摘要The optical properties and the band lineup in ganas/gaas single quantum wells (sqws) grown by molecular beam epitaxy (mbe) using photoluminescence (pl) technique were investigated. it was found that the low-temperature pl is dominated by the intrinsic localized exciton emission. by fitting the experimental datawith a simple calculation, band offset of the gan0.015as0.985/gaas heterostructure was estimated. moreover, deltae(c), the discontinuity of the conduction band was found to be a nonlinear function of the nitrogen composition (chi) and the average variation of deltae(c) is about 0. 110ev per % n, such smaller than that reported on the literature to (0.156 similar to 0.175 ev/n %). in addition, qc has little change whtn n composition increares, with an experimential relation of qc approximate tox(0.25). the band bowing coefficient (b) was also studied in this paper. the measured band bowing coefficient shows a strong function of chi, giving an experimental support to the theoretic calculation of wei su-huai and zunger alex (1996).
