英文摘要	: a microwave-modulated reflectance spectroscopy (mmrs) measurement system was constructed. this mmrs technique was used to identify a transition from holes in valence band to electrons in the ground subband (gs) of the two-dimensional electron system (2des) formed in a gaas/algaas heterostructure sample. the temperature (t) dependence of the mmrs shows a blue shift of the energy gap with increasing t, while the magnetic field (b) dependence of the mmrs shows a red shift of the energy gap with increasing b. both phenomena are attributed to the band-filling effect of holes in valence band in the gaas/algaas heterostructure. a theoretical simulation based on kramers-kronig relation was also presented which was similar with the experimental data.
