Electrostatically stabilized surface flat bands in rhombohedral graphite at zero displacement field
Kryštof Kolář, Andrea F. Young, Cyprian Lewandowski
Rhombohedral (ABC-stacked) multilayer graphene hosts interaction-driven phases enabled by surface flat bands at large displacement fields. In thick flakes, however, strong screenin…
Tunneling signatures of interband coherence in dilute exciton condensates
Kryštof Kolář, Felix von Oppen
We theoretically investigate signatures of exciton condensation and the underlying interband coherence in scanning tunneling microscopy. We consider both monolayer and bilayer cond…
Single-gate tracking behavior in flat-band multilayer graphene devices
Kryštof Kolář, Dacen Waters, Joshua Folk +2
A central feature of many van der Waals (vdW) materials is the ability to precisely control their charge doping, , and electric displacement field, , using top and bottom gat…
The electrostatic fate of -layer moiré graphene
Kryštof Kolář, Yiran Zhang, Stevan Nadj-Perge +2
Twisted -layer graphene (TNG) moiré structures have recently been shown to exhibit robust superconductivity similar to twisted bilayer graphene (TBG). In particular for an…
