Electron transport in folded bilayer-bilayer graphene/hexagonal boron nitride superlattices under high magnetic fields
Takuya Iwasaki, Motoi Kimata, Yoshifumi Morita +7
Employing graphene as a template, we fabricate moiré superlattices by stacking bilayer or folded bilayer-bilayer graphene (BLG or fBBLG) and hexagonal boron nitride (hBN), i.e., hB…
Topological Valley Currents in Bilayer Graphene/Hexagonal Boron Nitride Superlattices
Kosuke Endo, Katsuyoshi Komatsu, Takuya Iwasaki +8
Graphene superlattices have recently been attracting growing interest as an emergent class of quantum metamaterials. In this paper, we report the observation of nonlocal transport…
Observation of superconductivity in bilayer graphene/hexagonal boron nitride superlattices
Satoshi Moriyama, Yoshifumi Morita, Katsuyoshi Komatsu +9
A class of low-dimensional superconductivity (SC), such as most of "atomic-layer" SCs, has survived only under certain circumstances, implying a role of the substrate. Moreover, in…
Observation of the quantum valley Hall state in ballistic graphene superlattices
K. Komatsu, Y. Morita, E. Watanabe +4
In graphene superlattices, bulk topological currents can lead to long-range charge-neutral flow and non-local resistance near Dirac points. A ballistic version of these phenomena h…
