Title: Electronic and Thermoelectric Properties of CuCoO2

Abstract

Density functional calculations are used to elucidate the electronic structure and some transport properties of CuCoO{sub 2} . We find an electronic structure with similarities to Na{sub x}CoO{sub 2} , although it is much less two dimensional. In particular, there are narrow manifolds of t2{sub g} and e{sub g} states. Application of Boltzmann transport theory to the calculated band structure shows high thermopowers comparable to Na{sub x}CoO{sub 2} for both p - and n -type doping.
