A robust weak topological insulator in a bismuth halide Bi4Br2I2
Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11
We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…
Band alignment and interlayer hybridisation in transition metal dichalcogenide/hexagonal boron nitride heterostructures
S. J. Magorrian, A. J. Graham, N. Yeung +6
In van der Waals heterostructures, the relative alignment of bands between layers, and the resulting band hybridisation, are key factors in determining a range of electronic proper…
Large anomalous Hall effect induced by weak ferromagnetism in the noncentrosymmetric antiferromagnet
Hiroaki Tanaka, Shota Okazaki, Kenta Kuroda +13
We study the mechanism of the exceptionally large anomalous Hall effect (AHE) in the noncentrosymmetric antiferromagnet by angle-resolved pho…
Observation of Topological Superconductivity in a Stoichiometric Transition Metal Dichalcogenide 2M-WS2
Y. W. Li, H. J. Zheng, Y. Q. Fang +22
Topological superconductors (TSCs) are unconventional superconductors with bulk superconducting gap and in-gap Majorana states on the boundary that may be used as topological qubit…
Observation of topological electronic structure in quasi-1D superconductor TaSe3
Cheng Chen, Aiji Liang, Shuai Liu +21
Topological superconductors (TSCs), with the capability to host Majorana bound states that can lead to non-Abelian statistics and application in quantum computation, have been one…
Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator
Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28
The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
Indirect to direct gap crossover in two-dimensional InSe revealed by ARPES
Matthew Hamer, Johanna Zultak, Anastasia V. Tyurnina +16
Atomically thin films of III-VI post-transition metal chalcogenides (InSe and GaSe) form an interesting class of two-dimensional semiconductor that feature strong variations of the…
