Boron nitride substrates for high-quality graphene electronics.
TLDR
Graphene devices on h-BN substrates have mobilities and carrier inhomogeneities that are almost an order of magnitude better than devices on SiO(2).
Unconventional superconductivity in magic-angle graphene superlattices
TLDR
The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle.
One-Dimensional Electrical Contact to a Two-Dimensional Material
TLDR
In graphene heterostructures, the edge-contact geometry provides new design possibilities for multilayered structures of complimentary 2D materials, and enables high electronic performance, including low-temperature ballistic transport over distances longer than 15 micrometers, and room-tem temperature mobility comparable to the theoretical phonon-scattering limit.
Correlated insulator behaviour at half-filling in magic-angle graphene superlattices
TLDR
It is shown experimentally that when this angle is close to the ‘magic’ angle the electronic band structure near zero Fermi energy becomes flat, owing to strong interlayer coupling, and these flat bands exhibit insulating states at half-filling, which are not expected in the absence of correlations between electrons.
Direct-bandgap properties and evidence for ultraviolet lasing of hexagonal boron nitride single crystal
TLDR
HBN is shown to be a promising material for compact ultraviolet laser devices because it has a direct bandgap in the ultraviolet region and evidence for room-temperature ultraviolet lasing at 215 nm by accelerated electron excitation is provided.
Scanning tunnelling microscopy and spectroscopy of ultra-flat graphene on hexagonal boron nitride.
TLDR
Scanning tunnelling microscopy is used to show that graphene conforms to hBN, as evidenced by the presence of Moiré patterns, but contrary to predictions, this conformation does not lead to a sizeable band gap because of the misalignment of the lattices.
In-situ measurement of viscosity and density of carbonate melts at high pressure
We present the first measurements of carbonate melt viscosity and density at mantle pressures and temperatures and provide important data for modelling carbonatite behaviour within the mantle.…
Multicomponent fractional quantum Hall effect in graphene
Transferring graphene onto hexagonal boron nitride enables high-mobility multiterminal quantum Hall devices to be built. This makes it possible to study graphene's unique fractional quantum Hall…
Hunting for monolayer boron nitride: optical and Raman signatures.
We describe the identification of single- and few- layer boron nitride. Its optical contrast is much smaller than that of graphene but even monolayers are discernable by optimizing viewing…
Emergence of superlattice Dirac points in graphene on hexagonal boron nitride
It is well known that graphene deposited on hexagonal boron nitride produces moire patterns in scanning tunnelling microscopy images. The interaction that produces this pattern also produces a…
