Essay

The dissertation is devoted to the establishment of the laws of thermally stimulated formation of phase and structure composition of skutterudite CoSb3 based films, as well as the influence of the nanoscaling factor on their thermoelectric properties. Metallographic studies allowed to reveal the interval of thermal stability of phase composition and structure with enhanced homogeneity region of CoSb3 phase and minimal surface roughness, increased structure defectivity due to the antimony sublimation and grain size reduction, that, taking into account the nanoscale factor, leads to an increase in the coefficient of the thermoelectric efficiency of Co-Sb.
