Selective wet-etching of amorphous/crystallized Ag–As–S and Ag–As–S–Se chalcogenide thin films

Thermal annealing effect on the optical properties of Ag10As30S60 thin film

“…The optical parameters are sensitive to the annealing temperatures. The results suggest to control the optical properties of Ag 10 As 30 S 60 film. …”

“…The Ag 10 As 30 S 60 films are deposited by thermal evaporation technique. The transparency upon annealing for films is improved.…”

“…The optical properties of the Ag doped AsS thin films regarding different Ag content have been reported [8][9][10]. Refractive-index [11,12], and undoped and silver photodoped AsS amorphous thin films [13] have been studied.…”

Selective wet etching of amorphous As2Se3 thin films

“…Common photosensitivity together with generally low resistance of ChGs to the alkaline solutions can result in selective etching in both inorganic [2,3] and organic solutions [4,5]. Selectivity of the etching process can be significantly enhanced by photoinduced Ag dissolution into the exposed thin film [6]. In this case the photoinduced changes occur not only in the sample's structure but in its composition as well.…”

Structural study of AsS2–Ag glasses over a wide concentration range

“…Amorphous As-S chalcogenides with additions of Ag are of considerable interest due to their ionic conductivity, photo-induced Ag diffusion, polarity-dependent switching and memory effect [1][2][3][4][5][6][7][8]. Similar to As-S binary alloys, Ag-containing arsenic sulphides show a very good glass-forming ability over a wide concentration range [1].…”
