Abstract

The valence band dispersions for Bi₂Se₃ were determined using angle resolved photoelectron spectroscopy. The valence band maximum was found to be located at the γ point and was nondegenerate. The low k-space degeneracy of the valence band maximum (VBM) and the lesser degree of the anisotropy accounted for these materials poor thermoelectric properties as compared to that of Bi₂Te₃.
