High thermoelectric performance in oxides requires stable conductive materials that have suitable band structures. Here we show, based on an analysis of the thermopower and related properties using first-principles calculations and Boltzmann transport theory in the relaxation time approximation, that hole-doped Cu2O may be such a material. We find that hole-doped Cu2O has a high thermopower of above 200 μV K−1 even with doping levels as high as 5.2 × 1020 cm−3 at 500 K, mainly attributed to the…
