Abstract
Single crystals of CuInSe2 were prepared under conditions to suppress the occurrence of twinning. This was accomplished by growth from an In melt by the traveling heater method to keep the growth temperature below that of the sphalerite-chalcopyrite phase transition. The resulting crystals were n-type and could be converted to p-type by a Se anneal. Both n and p-type crystals were characterized structurally by X-ray diffraction, compositionally by microprobe analyses, morphologically by atomic force and scanning electron microscopy, and electrically. They were found to be mostly homogeneous with mirror-like cleavage and without twins.
