Technology for the crystal growth of ternary alloys of III-V compounds is usable in the field of IR detection. Photo detectors used in military, medical diagnosis and pollution monitoring devicesoperate in wave length range from 8 to 12 µm. The methods of crystal growth from melt like zone melting and Bridgman have been widely used for such intermetallic. The authors have usedBridgmanmethod because of the steady state growth obtainable with it. EDAX has been used for confirmation of constituent elements ofInTe:Bi. To obtain the band gap FTIR was used for IR Region.
