Abstract
The photoconductivity and IR-induced piezooptic effect of CuInS2 –ZnIn2 S4 solid solutions have been investigated. The results of studies of the photoconductivity spectra at T≈300 found that an increase in the concentration of Zn atoms you can smoothly change the position of the region of maximum photosensitivity to shorter wavelengths from ~0,8 μm for CuInS2 –ZnIn2 S4 and with 4 mol.% ZnIn2 S4 to ~ 0,73 μm for CuInS2 –ZnIn2 S4 with 16 mol.% ZnIn2 S4 . The most photosensitive were specimens with the 8 mol.% ZnIn2 S4 content. At lower temperatures (30-100 K) long-term relaxation processes of photoconductivity were observed. The temperature dependence of the piezooptic coefficients maximum corresponded to T ≈ 60 K for the alloys with various molar contents of ZnIn2 S4 . The highest values piezooptic coefficient was observed for the alloys CuInS2 -ZnIn2 S4 with 8 mol.% ZnIn2 S4 .
