Thermal conductivity of twisted bilayer graphene

Nanoscale, 2014
The heat carriers – phonons – in twisted bilayer graphene do not behave in the same manner as that observed in individual graphene layers.

Twist dependent magneto-optical response in twisted bilayer graphene

Journal of Physics: Condensed Matter, 2021
Abstract By employing a linearised Boltzmann equation, we calculate the magneto-optical properties of twisted bilayer graphene using non-magnetic wave functions. Both transverse and longitudinal responses are calculated up to the second order in applied magnetic field with their twist angle and Fermi level dependence examined. We find

Charge order and broken rotational symmetry in magic-angle twisted bilayer graphene

Nature, 2019
Bilayer graphene can be modified by rotating (twisting) one layer with respect to the other. The interlayer twist gives rise to a moiré superlattice that affects the electronic motion and alters the band structure1–4.

Real-Space Mapping of Local Subdegree Lattice Rotations in Low-Angle Twisted Bilayer Graphene.

Nano letters (Print), 2023
In two-dimensional small-angle twisted bilayers, van der Waals (vdW) interlayer interaction introduces an atomic-scale reconstruction, which consists of a moiré-periodic network of local subdegree lattice rotations. However, real-space measurement of the

Twisted bilayer graphene

2020
We continue the discussion of Van der Waals heterostructures for the case of twisted blayer graphene. After a general consideration, we discuss a special case of graphene dodecagonal quasicrystal for misorientation angle 30⁰. We also discuss a formation of flat bands for small misorientation angles and give a brief introduction to the physics of flat ...

Exceptional Magic Angles in Non-Hermitian Twisted Bilayer Graphene.

Physical Review Letters
Twisted bilayer graphene (TBG) features strongly correlated and topological phases due to its flat bands emerging near the magic angle. However, the effects of the non-Hermiticity, arising from the coupling to the environment and dissipation, have ...

Lattice reconstruction in twisted bilayer graphene

Journal of Physics: Condensed Matter
Abstract Twisted bilayer graphene (TBG) provides a tunable platform to study emergent properties that are absent in single-layer graphene by the van der Waals (vdW) interlayer interaction. The vdW interlayer interaction can also lead to notable lattice reconstruction at the interface, promoting interlayer commensurability while ...
