文摘

As30S70 thin films spin-coated from n-butylmine solution in optical quality Thermally induced increase of refractive index and decrease of optical bandgap Significant structural polymerization connected with film densification Exposure induced changes of chemical stability (positive wet-etching) Stable As/S atomic ratio within films volume proved by HS-LEIS spectroscopy
