Gate-defined Josephson weak-links in monolayer
Michael D. Randle, Masayuki Hosoda, Russell S. Deacon +9
Systems combining superconductors with topological insulators offer a platform for the study of Majorana bound states and a possible route to realize fault tolerant topological qua…
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…
Josephson junctions of Weyl semimetal induced by spontaneous nucleation of superconductor
Manabu Ohtomo, Russell S. Deacon, Masayuki Hosoda +7
We report on the fabrication of Josephson junction devices with weak links utilizing the Weyl and higher-order topological semimetal . We show that $\text{WTe}_2\text…
Small bandgap features achieved in atomically precise 17-atom-wide armchair-edged graphene nanoribbons
Junichi Yamaguchi, Hironobu Hayashi, Hideyuki Jippo +9
Graphene nanoribbons (GNRs) synthesized using a bottom-up technique potentially enable future electronic devices owing to the tunable electronic structures depending on the well-de…
The high hydrogen adsorption rate material based on graphane decorated with alkali metals
Liubov Yu. Antipina, Pavel V. Avramov, Seiji Sakai +5
The graphane with chemically bonded alkali metals (Li, Na, K) was considered as potential material for hydrogen storage. The ab initio calculations show that such material can adso…
