Tetrahedrite exhibits favorable thermoelectric properties, while also being composed of non-toxic and earth-abundant elements. Although tetrahedrite has been studied extensively as a p-type thermoelectric, n-type behavior in this material has not yet

Tetrahedrite offers advantages over state-of-the-art thermoelectrics, such as lead telluride, because of its low cost and environmentally friendly composition. However, typical sealed-tube synthesis of tetrahedrite can require multiple days or weeks.

Cobalt monosilicide (CoSi) prepared by arc melting possesses a very high thermoelectric power factor of 60 μW cm−1 K−2 at room temperature. The high lattice thermal conductivity of CoSi, however, limits its thermoelectric efficiency. In this pap
