Revealing the conduction band and pseudovector potential in 2D moiré semiconductors
Abigail J. Graham, Heonjoon Park, Paul V. Nguyen +12
Stacking monolayer semiconductors results in moiré patterns that host many correlated and topological electronic phenomena, but measurements of the basic electronic structure under…
Observation of Γ-valley moiré bands and emergent hexagonal lattice in twisted transition metal dichalcogenides
Ding Pei, Binbin Wang, Zishu Zhou +19
Twisted van der Waals heterostructures have recently been proposed as a condensed-matter platform for realizing controllable quantum models due to the low-energy moiré bands with s…
Domain dependent Fermi arcs observed in a striped phase dichalcogenide
T. Mizokawa, A. Barinov, V. Kandyba +11
Angle-resolved photoemission spectromicroscopy on IrTe2 reveals evolution of mesoscopic striped domains across its first order phase transition at about 280 K. The striped texture…
Observation and control of the weak topological insulator state in ZrTe5
Peng Zhang, Ryo Noguchi, Kenta Kuroda +14
A quantum spin Hall insulator hosts topological states at the one-dimensional edge, along which backscattering by nonmagnetic impurities is strictly prohibited and dissipationless…
Moiré superlattice effects and band structure evolution in near-30-degree twisted bilayer graphene
Matthew J. Hamer, Alessio Giampietri, Viktor Kandyba +6
In stacks of two-dimensional crystals, mismatch of their lattice constants and misalignment of crystallographic axes lead to formation of moiré patterns. We show that moiré superla…
Ghost anti-crossings caused by interlayer umklapp hybridization of bands in 2D heterostructures
Abigail J. Graham, Johanna Zultak, Matthew J. Hamer +13
In two-dimensional heterostructures, crystalline atomic layers with differing lattice parameters can stack directly one on another. The resultant close proximity of atomic lattices…
Direct evidence for flat bands in twisted bilayer graphene from nano-ARPES
Simone Lisi, Xiaobo Lu, Tjerk Benschop +21
Transport experiments in twisted bilayer graphene revealed multiple superconducting domes separated by correlated insulating states. These properties are generally associated with…
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…
Visualizing electrostatic gating effects in two-dimensional heterostructures
Paul V. Nguyen, Natalie C. Teutsch, Nathan P. Wilson +9
The ability to directly observe electronic band structure in modern nanoscale field-effect devices could transform understanding of their physics and function. One could, for examp…
Band offset and gap tuning of tetragonal CuO-SrTiO3 heterojunctions
Giovanni Drera, Alessio Giampietri, Alfredo Febbrari +3
In this work we analyze the electronic structure at the junction between a SrTiO3 (001) single crystal and a thin tetragonal CuO layer, grown by off-axis RF-sputtering. A detailed…
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…
Discovery of switchable weak topological insulator state in quasi-one-dimensional bismuth iodide
R. Noguchi, T. Takahashi, K. Kuroda +16
The major breakthroughs in the understanding of topological materials over the past decade were all triggered by the discovery of the Z topological insulator (TI). In three dim…
