Abstract
Solid state reaction by sintering the finely powdered starting binary compounds, Cu2S and In2S3 was carried out to prepare homogeneous and stoichiometric CuInS2 crystals. Perfectly densified (with 100% theoretical density) and highly oriented CuInS2 crystals were obtained by sintering and annealing at 1050°C for 60 hours followed by slow cooling, using a pressed compact of the starting materials within a closely fitted carbon crucible. Appearance of the preferred (112) top surface of the crystal is utilized as a substrate crystal for homoepitaxial growth.Keywords
