Abstract

In the present work the photochemical reaction in Cd_1-xZn_xS(Se) films considered depending on technological modes of their deposition and heat treatment (HT). In Cd_1-xZn_xS(Se) films the formation of Cd_i-Cd_i, Zn_i-Zn_i, V_Se-Zn_i etc. associations provides occurrence of optical active electronic states carried in an interval of energy 0.3-0.6 eV allows using of a Cd_1-xZn_xS(Se) films for creation on their basis non-cooled photodetectors in the IR-range. At illumination by light of λ=0.95 μm were observed anomalous photoconductivity and photomemory phenomenon connected with existence in them defects with metastable states which concentration can be operated depending on structure deposition and heat treatment (HT) mode and limits by tunnel transitions of no basic located electrons and holes between r- and s-centres. In Cd_1-xZn_xS(Se) films after HT on air during 10-15 minutes was observed the photochemical reaction with activation energy of 0.17-0.21 eV representing disintegration process of donor-acceptor pairs consisting of the r-centres and the Cd_i, Zn_i donors at illumination with light of λ=1.25 μm and caused by precipitation conditions and HT.
