Imaging flat band electron hydrodynamics in biased bilayer graphene
Canxun Zhang, Evgeny Redekop, Hari Stoyanov +12
Hydrodynamic electron transport arises when carrier kinetics are dominated by interelectron collisions rather than the relaxation of momentum out of the electron system. In recent…
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…
Nanoscale infrared and microwave imaging of stacking faults in multilayer graphene
Ludwig Holleis, Liam Cohen, Noah Samuelson +14
Graphite occurs in a range of metastable stacking orders characterized by both the number and direction of shifts between adjacent layers by the length of a single carbon-carbon bo…
Superconductivity and quantized anomalous Hall in rhombohedral graphene
Youngjoon Choi, Ysun Choi, Marco Valentini +8
Inducing superconducting correlations in chiral edge states is predicted to generate topologically protected zero energy modes with exotic quantum statistics. Experimental efforts…
Visualizing incommensurate inter-valley coherent states in rhombohedral trilayer graphene
Yiwen Liu, Ambikesh Gupta, Youngjoon Choi +13
ABC-stacked rhombohedral graphene multilayers exhibit a wide variety of electronic ground states characterized by broken isospin symmetry and superconductivity. Recently, indirect…
