Abstract:

Photoluminescence and wavelength-modulated transmission spectra of Ag3AsS3 crystals were investigated at 10 K Ag3AsS3 structures with Ag2S layers were obtained by chemical and electrochemical methods. It was shown that nanolayers with Ag2S quantum dots can be formed on the surface. The current-voltage characteristics, impedance, and photoeffect of these structures were studied depending on the applied voltage polarities. The time dependences of Ag–Ag2S–Ag3AsS3/heterostructure conductivity at different voltages applied to the illuminated contact were studied.
