Single crystals of Cu0.5Ag0.5InSSe pentenary alloy were successfully grown by chemical vapor transport technique using iodine as the transporting agent. X-ray analysis was carried out to determine the structural parameters. Microstructures and morphological patterns on the surface of the grown crystals were observed which show the type of growth mechanisms involved in growth of this crystal. Microhardness analysis was also carried out for the grown crystals.
