Here we show based on an analysis of the thermopower and related properties using first-principles calculations and Boltzmann transport theory that hole doped Cu2O may be such a material. We find that hole-doped Cu2O has a high thermopower of above 200 microV/K even with doping levels as high as 5.5x10 20 cm-3 at 500 K, mainly attributed to the heavy valence bands of Cu2O. This is reminiscent of the cobaltate family of high performance oxide thermoelectrics and implies that hole-d","authors_text":"David J.
