We report a study of the valence-band electronic structure of the newly discovered thermoelectric material, CsBi4Te6, using angle-resolved photoelectron spectroscopy. This material exhibits quasi-one-dimensional behavior, which is related to its unique crystal structure. The highly anisotropic band dispersions might explain the large value of the figure of merit, ZT, observed in the hole-doped systems. Our experimental results are compared with a recent theoretical band-structure calculation.
