Khanova G. Development of physico-technological bases manufacturing of samarium sulphide films for strain gages and study of their parameters

By the chemical method of decomposition of sulphide containing chelate metalorganic compounds the polycrystalline textured films of samarium sulphide line have been received from the synthesised and investigated complexes of samarium. Both the conditions for cubic monosulphide samarium manufacturing and ones for high tensosensitive reproducible SmS films obtained by vacuum techniques have been determined. Recombination parameters, charge flow mechanisms and influence of a material of contacts in thin-films structures on the base of samarium monosulphide have been investigated. Metrological characteristics of samarium semiconductings films have been determined, the main features of topology of SmS semiconducting strain gages are formulated and some advantages of such strain gages in comparison with metal foil strain gages have been shown.
