  • The thermoelectric properties of the layered oxides K x RhO 2 (x = 1/2 and 7/8) are investigated by means of the electronic structure, as determined by ab inito calculations and Boltzmann transport theory. In general, the electronic structure of K x RhO 2 is similar to Na x CoO 2 , but with strongly enhanced transport. K 7/8 RhO 2 exceeds the ultrahigh power factor of Na 0.88 CoO 2 reported previously by more than 50%. The roles of the cation concentration and the lattice parameters in the… CONTINUE READING
