Iron solubility in SnTe

Abstract

Tin telluride doped with varying amounts of iron has been synthetized and analysed by electrical measurements (electrical conductivity and Hall effect), X-ray analysis and Mössbauer spectroscopy. These measurements have established the order of magnitude of the iron solubility and its influence on the transport properties. It was found that: a) the iron solubility was very low; b) the electrical properties of the tin telluride were not significantly affected by the iron dopant.
