(Ag₃AsS₃)x(As₂S₃)₁₋x (x = 0.3; 0.6; 0.9) thin films were deposited onto a silica substrate by rapid thermal evaporation. The amount of Ag-rich crystalline phase precipitates on the surfaces of the films increases with ...

Cu₆(P₁₋xAsx)S₅I mixed crystals were grown using chemical vapour transport. Temperature isoabsorption investigations of optical absorption edge enable to reveal anomalies typical for the first- and second-order phase ...
