dc.description.abstractWe compute the spin-active scattering matrix and the local spectrum at the interface between a metal and a three-dimensional topological band insulator. We show that there exists a critical incident angle at which complete (100%) spin-flip reflection occurs and the spin-rotation angle jumps by π. We discuss the origin of this phenomena, and systematically study the dependence of spin-flip and spin-conserving scattering amplitudes on the interface transparency and metal Fermi-surface parameters. The interface spectrum contains a well-defined Dirac cone in the tunneling limit and smoothly evolves into a continuum of metal-induced gap states for good contacts. We also investigate the complex band structure of Bi2 Se3. © 2010 The American Physical Society.
