The Role of Cation Deficiency and Impurities in the Formation of Photosensitivity Centers in CdIn2S4 Compound
Year: 2025
Type: article
Abstract: Optical quenching of photocurrent, the dependence of the quenching magnitude on the wavelength of the additional quenching light, and temperature were studied in stoichiometric, nonstoichiometric, and copper-doped CdIn2S4 samples. It was shown that a deficiency of cadmium and indium in CdIn2S4 does not change the energy distance of slow recombination centers from the valence band top ( $$E_{{{\text{vr}}}}^{{\text{0}}}$$ = 0.73 eV for both undoped samples and those with cadmium and indium deficiency), whereas doping the crystals with copper leads to a slight increase in this energy distance ( $$E_{{{\text{vr}}}}^{{\text{0}}}$$ = 0.86 eV).
