Abstract

- The electronic structures of atomically thin layers of bismuth telluride (Bi2Ti3) have been studied by using density functional theory. It is found that quintuple layers of Bi2Te3 are semiconductor with localized shallow bands. The weak covalent Bi-Te-2 interaction in quintuple layer allows to further exfoliate it to form bilayer and trilayer sheets. In the latter cases, the valence electrons cannot fully occupy all the valence bands and the sheets become metallic.
