Cryogenic shock exfoliation for ultrahigh mobility rhombohedral graphite nanoelectronics
Ludwig Holleis, Youngjoon Choi, Canxun Zhang +16
Rhombohedral multilayer graphene (RMG) offers a highly tunable platform for correlated electron physics, featuring field-effect control of magnetic, superconducting, and topologica…
Visualizing orbital magnetism in electron doped rhombohedral multilayer graphene
Owen I. Sheekey, Trevor B. Arp, Benjamin A. Foutty +24
Electron doped rhombohedral multilayer graphene at high displacement field features an exceptionally flat band minimum with near-ideal quantum geometry. Experiments in this regime…
Imaging the Meissner effect and local superfluid stiffness in a graphene superconductor
Ruoxi Zhang, Benjamin A. Foutty, Owen Sheekey +15
We report the observation of the Meissner effect in a rhombohedral graphene superconductor, realized via direct imaging of the static fringe magnetic field. In our few-micron sampl…
Flat band surface state superconductivity in thick rhombohedral graphene
Yi Guo, Owen I. Sheekey, Trevor Arp +11
Rhombohedral multilayer graphene has recently emerged as a rich platform for studying correlation driven magnetic, topological and superconducting states. While most experimental e…
Magnetic Hofstadter cascade in a twisted semiconductor homobilayer
Benjamin A. Foutty, Aidan P. Reddy, Carlos R. Kometter +4
Transition metal dichalcogenide moiré homobilayers have emerged as a platform in which magnetism, strong correlations, and topology are intertwined. In a large magnetic field, the…
