Type: conference-abstract

Abstract: We investigated the effect of heat treatment on Cu(Ga1-x In x ) y S z (1<y<5) bulk crystals under Cu vapor atmosphere. The alloy compositions of as-grown crystal surfaces changed into CuGa1-x'In x'S2 after CuI heat treatment. The crystal structures also changed to the chalcopyrite from OVC (ordered vacancy compound) or hexagonal structures. Similar changes in the alloy compositions were observed after Cu2S heat treatment for crystals with as-grown alloy compositions of 1<y<3. However, as-grown crystals with compositions of 3<y<5 showed only small changes in alloy composition toward Cu(Ga,In)3S5.
