| Research Abstract |
CuInS_2 films with various [Cu]/[In] ratios were deposited by sputtering alternatively Cu- and In-facing-targets under Ar-diluted CS_2 atmosphere. Composition of the films corresponded to the (Cu_xS)-(CuInS_2)-(CuIn_5S_8)-(In_2S_3) system line. Stoichiometric CuInS_2 films exhibited the absorption-edge corresponding to the energy-gap of CuInS_2. In CuInS_2 epitaxial films by multisource evaporation method, lattice strain as well as the [Cu]/[In] ratio was considered to be related with growth mechanism.
