Opportunities and Challenges in Twisted Bilayer Graphene: A Review
Nano-Micro Letters, 2020 Two-dimensional (2D) materials exhibit enhanced physical, chemical, electronic, and optical properties when compared to those of bulk materials. Graphene demands significant attention due to its superior physical and electronic characteristics among ...

Tuning superconductivity in twisted bilayer graphene [PDF]
Science, 2019 Upping the pressure in bilayer graphene The discovery of superconductivity and exotic insulating phases in twisted bilayer graphene has established this material as a model system of strongly correlated electrons. To achieve superconductivity, the two layers of graphene need to be at a very precise angle with respect to each ...

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.

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.
