The III-V intennetallic compounds are important for un-cooled long wavelength infrared (LWIR) photo detectors. The authors have prepared thin films of n-InBi1-xSbx and InBi1-xSex on p-Si wafer to prepare the heterojunctions under the vacuum of the order of 10-5 torr. The I-V (current and voltage) characteristics of these junctions have been studied. The results are reported and implications are discussed.
