Recently, CsBi4Te6 has been reported as a high-performance thermoelectric material for low temperature applications with a higher thermoelectric figure of merit (ZT ∼ 0.8 at 225 Kelvin) than conventional Bi2-xSbxTe3-ySey alloys at the same temperature. First-principle electronic structure calculations within density functional theory performed on this material give an indirect narrow-gap semiconductor. Dispersions of energy bands along different directions in k-space display large anisotropy and multiple conduction band minima close in energy, characteristics of a good thermoelectric material.
