HPHT synthesis and enhanced TE performance of Te and Sn/Se elements binary-doped CoSb3

“…The small grain size and rich grain boundaries are helpful for strengthening phonon scattering, thus reducing the lattice thermal conductivity. 17,18 Figures 2(a)-2(c) represent the HRTEM micrographs of Co 4 Sb 11ÀxÀy Te x Sn y /Se y bulk composite synthesized by HPHT at 2.5 GPa to explore the effect of high pressure on microstructures. We can observe that the lattices orientation is disordered (see double-headed arrows), and the distinct lattice bending appears as dislocations appear in lattices which are shown in Figs.…”
