Investigation of cadmium alternatives in thin-film coatings

Study of the hydrostatic pressure on orthorhombic IV–VI compounds including many-body effects

“…Also, they have been studied for the evaluation of nanostructures etching [10]. In particular, SnS and SnSe have been used as shells for PbSe and PbS quantum dots, for the development of infrared-based devices [11], and as alternative for Cadmium in IR thin film coatings [12]. These compounds crystallize in an orthorhombic structure (Pnma 62 ðD 16 2h Þ space group) and form double layers that are perpendicular to the direction of the unit cell largest axis.…”

Investigation of Sn-Based Alternatives to Cadmium in Thin Film Coatings

“…Thin films containing cadmium are employed in a variety of optoelectronic applications where they offer distinct mechanical and optical advantages over other coating materials [3][4][5]. The potential of many binary and ternary Sn-based compounds as replacements for cadmium in solar cells and mid-infrared filtering has been discussed elsewhere [6]. Thin films of SnS x Se 1-x previously deposited by thermal evaporation are seen to display comparable infrared transparency to some Cd-based coatings.…”
