中文摘要	the first report of a short wavelength infrared detector based on type ii inas/gasb superlattices is presented. very short period superlattices containing inas (2ml)/gasb (8ml) superlattices (sls) were grown by molecular-beam epitaxy on gasb substrates. the photoluminescence showed a cut-off wavelength at 2.1 mu m at 10 k and 2.6 mu m at 300 k. room-temperature optical transmittance spectra shows obvious absorption in inas (2ml)/gasb (8ml) sl in the range of 450-680 mev, i.e. 1.8-2.7 mu m. the cut-off wavelength moved from 2.3 mu m to 2.6 mu m with temperature rising from 77 k to 300 k in photoresponse spectra. the blackbody response r-v exponentially decreased as a function of 1/t in two temperature sections (130-200 k and 230-300 k). the blackbody detectivity d-bb(center dot) was beyond 1 x 10(8) cmhz(1/2)/w at room temperature.
