Thermopower in hBN/graphene/hBN superlattices
Victor H. Guarochico-Moreira, Christopher R. Anderson, Vladimir Fal'ko +9
Thermoelectric effects are highly sensitive to the asymmetry in the density of states around the Fermi energy and can be exploited as probes of the electronic structure. We experim…
Mapping quantum Hall edge states in graphene by scanning tunneling microscopy
T. Johnsen, C. Schattauer, S. Samaddar +7
Quantum Hall edge states are the paradigmatic example of the bulk-boundary correspondence. They are prone to intricate reconstructions calling for their detailed investigation at h…
Interfacial ferroelectricity in marginally twisted 2D semiconductors
Astrid Weston, Eli G Castanon, Vladimir Enaldiev +19
Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of novel metamaterials. Here we demonstrate a room-temperature ferroelectric semico…
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…
Control of electron-electron interaction in graphene by proximity screening
M. Kim, S. G. Xu, A. I. Berdyugin +14
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One…
