Electronic structure of Bi{sub 2}Te{sub 3} studied by angle-resolved photoemission
Abstract
We report a detailed study of the electronic structure of Bi{sub 2}Te{sub 3}, to our knowledge the best room temperature thermoelectric material known to date, using angle-resolved photoemission. Dispersions of the valence bands were determined. A sixfold k-space degeneracy in the valence-band maximum is found. The quasi-two-dimensional nature of the electronic structure was demonstrated by the weakly dispersive bands along the {Gamma}-Z direction. Experimental results are compared with theoretical band-structure calculations and with de Haas--van Alphen and Shubnikov--de Haas experiments.
