Abstract

Abstract : We report on the synthesis of Sb2 Te3 nanoparticles with zT values of up to 1.5. The thermoelectric transport parameters were independently optimized, giving guidance for the design of thermoelectric materials. Abstract : We report on the synthesis of Sb2 Te3 nanoparticles with record-high figure of merit values of up to 1.5. The central thermoelectric parameters, electrical conductivity, thermal conductivity and Seebeck coefficient, were independently optimized. The critical influence of porosity for the fabrication of highly efficient thermoelectric materials is firstly demonstrated, giving a strong guidance for the optimization of other thermoelectric materials.
