Chiral Tunnelling in Twisted Graphene Bilayer [PDF]

Physical Review Letters, 2013
The perfect transmission in graphene monolayer and the perfect reflection in Bernal graphene bilayer for electrons incident in the normal direction of a potential barrier are viewed as two incarnations of the Klein paradox.

Elastocapillary cleaning of twisted bilayer graphene interfaces [PDF]

Nature Communications, 2021
Here, the authors investigate the long-range interaction and coalescence mechanism of water and ethanol nanopockets encapsulated in twisted bilayer graphene, showing the complete recovery of moiré patterns after the motion of the contaminants.

Twisted Bilayer Graphene: A Phonon Driven Superconductor

Physical Review Letters, 2019
We study the electron-phonon coupling in twisted bilayer graphene (TBG), which was recently experimentally observed to exhibit superconductivity around the magic twist angle $\theta\approx 1.05^\circ$.

Unusual magnetotransport in twisted bilayer graphene. [PDF]

Proc Natl Acad Sci U S A, 2022
Significance When two sheets of graphene are twisted to the magic angle of 1.1 ∘ , the resulting flat moiré bands can host exotic correlated electronic states such as superconductivity and ferromagnetism. Here, we show transport properties of a twisted bilayer graphene device at 1.38 ∘

Graphene bilayers with a twist [PDF]

Nature Materials, 2020
Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid to a strongly correlated two-dimensional electron system with properties that are extraordinarily sensitive to carrier density and to controllable environmental factors such as the proximity of nearby gates and twist-angle variation.

Ultrahigh Ballistic Resistance of Twisted Bilayer Graphene

Crystals, 2021
Graphene is a good candidate for protective material owing to its extremely high stiffness and high strength-to-weight ratio. However, the impact performance of twisted bilayer graphene is still obscure.

Evidence for unconventional superconductivity in twisted bilayer graphene [PDF]

Nature, 2021
The emergence of superconductivity and correlated insulators in magic-angle twisted bilayer graphene (MATBG) has raised the intriguing possibility that its pairing mechanism is distinct from that of conventional superconductors1–4, as described by the ...

Strain fields in twisted bilayer graphene [PDF]

Nature Materials, 2021
Van der Waals heteroepitaxy allows deterministic control over lattice mismatch or azimuthal orientation between atomic layers to produce long wavelength superlattices. The resulting electronic phases depend critically on the superlattice periodicity as well as localized structural deformations that introduce disorder and strain.
