Yh. Choi et al., GROWTH OF IN1-XTLXSB A NEW INFRARED MATERIAL, BY LOW-PRESSURE METALORGANIC CHEMICAL-VAPOR-DEPOSITION, Applied physics letters, 63(3), 1993, pp. 361-363
We report the growth of In1-xTlxSb, a new III-V alloy for long-wavelen
gth infrared detector applications, by low-pressure metalorganic chemi
cal vapor deposition. In1-xTlxSb with good surface morphology was obta
ined on both GaAs and InSb substrates at a growth temperature of 455-d
egrees-C. X-ray diffraction measurements showed resolved peaks of In1-
xTlxSb and InSb films. Infrared absorption spectrum of In1-xTlxSb show
ed a shift toward lower energies compared to InSb spectrum. Hall mobil
ity data on In1-xTlxSb/InSb/GaAs structure showed enhanced mobility at
low temperatures compared to InSb/GaAs structure.
