Rotational Disorder in Twisted Bilayer Graphene

ACS Nano, 2014
Conventional means of stacking two-dimensional (2D) crystals inevitably leads to imperfections. To examine the ramifications of these imperfections, rotational disorder and strain are quantified in twisted bilayer graphene (TBG) using a combination of Raman spectroscopic and low-energy electron diffraction imaging.

Twinning and Twisting of Tri- and Bilayer Graphene

Nano Letters, 2012
The electronic, optical, and mechanical properties of bilayer and trilayer graphene vary with their structure, including the stacking order and relative twist, providing novel ways to realize useful characteristics not available to single layer graphene.

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 ...

Bending Moiré in Twisted Bilayer Graphene

The Journal of Physical Chemistry Letters
Moiré potentials caused by lattice mismatches significantly alter electrons in two-dimensional materials, inspiring the discovery of numerous unique physical properties. While strain modulates the structure and symmetry of the moiré potential, serving as a tuning mechanism for interactions, the impact of out-of-plane deformation, e.g., bending, on the ...

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 ...
