Topological nature and the multiple Dirac cones hidden in Bismuth high-Tc superconductors
Recent theoretical studies employing density-functional theory have predicted BaBiO(3) (when doped with electrons) and YBiO(3) to become a topological insulator (TI) with a large topological gap (~0.7 eV). This, together with the natural stability against surface oxidation, makes the Bismuth-Oxide f...
