Relativistic effects and fully spin-polarized Fermi surface at the Tl/Si(111) surface

We present a detailed analysis of the relativistic electronic structure and the momentum-dependent spin-polarization of the Tl/Si(111) surface. Our first-principle calculations reveal the existence of fully spin-polarized electron pockets associated to the huge spin-splitting of metallic surface ban...
