WebApr 12, 2024 · We have shown that isolated bismuth ad-atoms diffuse much too readily to be observed in an STM experiment. However, when a diffusing bismuth ad-atom encounters a pair of chlorine atoms in the Cl1 or Cl2 configurations, structures f1 or f2 are formed with an energy gain of 0.27 and 0.22 eV, respectively, [Figs. 1(g), 1(h), and 3(a)]. … WebHere, we establish that the electronic structure of bismuth, an element consistently described as bulk topologically trivial, is in fact topological and follows a generalized bulk–boundary correspondence of higher-order: not the surfaces of the crystal, but its hinges host topologically protected conducting modes.
