سنتز چهره و تجزیه و تحلیل حرارتی نانوساختارهای تلورید آنتیموان

Fabrication of nano-sized thermoelectric (TE) semiconductors like Antimony chalcogenides and study of their properties is a growing interest among the inorganic thermoelectric (TE) materials, which leads to the increase in the efficiency of energy conversion. The demand for fabricating high performance Thermoelectric (TE) materials in large quantity is very high. A facile synthesis was carried out for nanostructures of Sb2Te3 material trough chemical precipitation and solvo-thermal route. Both these chemical synthesis routes are not complicated and are suitable for expeditious way of synthesizing Nano crystallites, but have their own advantages. The structural and morphological studies of the prepared nanostructure material were carried out by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The thermal studies were carried by Non destructive Thermal Analysis. Measurements of the thermal conductivity of the prepared nanostructured powders indicate that these synthesized Sb2Te3 material can be tuned to enhance the thermoelectric (TE) behavior as they possess considerably low thermal conductivity than that of bulk Sb2Te3.
