Emergent One-Dimensional Helical Channel in Higher-Order Topological Insulators with Step Edges
Akihiko Sekine, Manabu Ohtomo, Kenichi Kawaguchi +1
We study theoretically the electronic structure of three-dimensional (3D) higher-order topological insulators in the presence of step edges. We numerically find that a 1D conductin…

Electronic properties of the steps in bilayer Td-WTe2
Mari Ohfuchi, Akihiko Sekine, Manabu Ohtomo +1
Monolayer WTe2 stripes are quantum spin Hall (QSH) insulators. Density functional theory was used for investigating the electronic properties of the stripes and steps in bilayer Td…
