Silicides: Promising Thermoelectric Materials

Higher transition metal silicides are very well-suited for anisotropic thermoelectric conversion. Essential anisotropy of the Seebeck coefficient, together with good mechanical properties, allows production of reliable anisotropic thermoelectric converters.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
