Tetrahedrites, naturally occurring sulfosalt minerals, have been shown to exhibit peak ZT values close to unity near 700 K due to the combination of semiconducting-like properties and extremely low lattice thermal conductivity. A wide range of elements can be substituted into tetrahedrites, each of them affecting the thermoelectric properties. Interestingly, all tetrahedrites reported to date contain exclusively d- and p-block elements of the periodic table. Here, we demonstrate that magnesium, an s-block element, can be introduced in Cu12Sb4S13.
