...Mian Liu; Changsong Liu; Xiaoying Qin In this study, first-principles electronic structure calculations and Boltzmann transport theories were used to understand the thermoelectric behavior of tetrahedrites. Calculations were performed on zinc (Zn)-substituted derivatives with zinc occupying each...

...Daniel Thompson, PhD; Dale Hitchcock, MS; Ali Lahwal, MS; T. M. Tritt, PhD Various compositions of the thermoelectric material, silicon germanium (SiGe), were synthesized directly from single elements (SE) via the spark plasma sintering (SPS) process. Through proper choice of commercially available...
