Thermoelectric properties of Gd and Se double substituted tetrahedrite.

The compound CuSbS, known as tetrahedrite, is an eco-friendly p-type thermoelectric material with earth-abundant, low-cost, and less toxic constituents. This contemporary work studied the thermoelectric properties of Gd and Se double-substituted tetrahedrites. The samples with nominal composition CuGdSbSSe (where = 0, 0.
