Anisotropy in thermoelectric properties of textured ZnSb nanomaterial by high Zn occupancy (132) crystallographic planes

This study reports the cost-effective synthesis of textured ZnSb nanomaterials via spark plasma sintering, revealing that anisotropic thermoelectric properties arise from preferential crystallographic orientations where higher Zn occupancy on (132) planes enhances the Seebeck coefficient while electrical conductivity is maximized along the (211) planes.
