Abstract
Tin Telluride is an efficient thermoelectric material having high power factor and low thermal conductivity. Pristine SnTe and Te rich SnTe were synthesized by using solvothermal method. Structural study of these samples was carried out by using Powder XRD and FESEM. Electron density maps show the uniformity of crystal structure in space. FESEM micrographs also show the formation of nanoparticles. There is formation of second phase of Te in Te rich SnTe. Crystallite size decreases, lattice strains, stacking faults and dislocation densities increase in Te rich SnTe. These distortions in structural properties can be useful in reduction of lattice thermal conductivity. Hence Te rich SnTe can be an efficient compound for thermoelectric power generation.
