Abstract

We report a study of the valence-band electronic structure of the newly discovered thermoelectric material, (formula presented) 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, (formula presented) observed in the hole-doped systems. Our experimental results are compared with a recent theoretical band-structure calculation.
