Synthesis, Phase Engineering and Optoelectronic Applications of Binary Arsenic Sulphide Thin Films from Orpiment to Dimorphite

Binary arsenic sulphide contains three thermodynamically stable compounds, orpiment (As2S3), realgar (As4S4) and dimorphite (As4S3), spanning a covalent layer network at the sulphur-rich end and discrete molecular cages at the arsenic-rich end. Thin-film research has concentrated...
