Synthesis of SnSe films obtained by magnetron sputtering

Abstract

This work presents a study of SnSe thin films obtained by RF magnetron sputtering, which is a technology relatively cheap and easy for devices based on thin film, unlike most SnSe fabrication techniques for thermoelectric applications already present in the literature. In this study we characterize the optical, electrical and compositional properties of the materials. SnSe films deposited by magnetron sputtering, demonstrate low thermal conductivity substantially below that of the single crystal A-axis. A low thermal conductivity is useful for the development of thermoelectric generators, but it is also of interest for the development of other devices based on SnSe films such as solar cells, etc.
