Aging of the surface of Bi(2)Se(3)

Materials Science 2014-11-05 v1

Abstract

We study the electronic structure of Bi(2)Se(3) employing high resolution photoemission spectroscopy and discover the dependence of the behavior of Dirac particles on surface terminations. The Dirac cone apex appears at different energies and exhibits contrasting shift on Bi and Se terminated surface with complex time dependence emerging from subtle adsorbed oxygen-surface atom interactions. These results uncover the surface states behavior of real systems possessing topologically ordered surface.
