Properties of CdSb thin films obtained by RF sputtering

Preparation and laser modification of optically selective multilayer film structures on the In4Se3, In4(Se3)1-х(Te3)х and CdSb crystals

“…The stability and resistance to chemical agents and the atmosphere of these crystals make it possible to create photovoltaic and optical elements on their basis 5,6 . Along with these crystals, it is worth considering crystals of another group -CdSb, since the width of the band gap of CdSb Eg = 0.48 eV is almost the same as that of In4Te3, with λcut = 2.5 μm 7 . An important issue is to study the effect of laser treatment (LT) on their spectral and photosensitive characteristics, to improve the technology of obtaining thin film cutoff interference filters and photosensitive heterojunctions for the formation of elements related to the filtration and registration of radiation in the infrared range 8,9 .…”
