Compounds based on the natural mineral tetrahedrite exhibit thermoelectric properties comparable to state of the art materials. Tetrahedrites are semiconductors with large Seebeck coefficients and low electrical resistivity. Additionally, a highly anharmonic phonon spectrum gives rise to minimal lattice thermal conductivity. Natural tetrahedrite mineral may be used as a low cost, earth-abundant source material for high performance thermoelectricity.
