Spin coated amorphous chalcogenide films: Thermal properties

摘要

The annealing behavior of spin coated thin films prepared from solutions of As2S3 dissolved in n‐propylamine and n‐butylamine has been investigated using IR, mass spectrometry, thermogravimetric analysis, and scanning calorimetry. As prepared films containing arsenic sulfide glass domains with surfaces reacted as alkyl ammonium salt undergo loss of amine and hydrogen sulfide during heating. H2S removal is believed to be accompanied by cross linking of glass domains resulting in a network glass containing only arsenic and sulfur.
