Twisting Bilayer Graphene Superlattices

ACS Nano, 2013
Bilayer graphene is an intriguing material in that its electronic structure can be altered by changing the stacking order or the relative twist angle, yielding a new class of low-dimensional carbon system. Twisted bilayer graphene can be obtained by (i) thermal decomposition of SiC; (ii) chemical vapor deposition (CVD) on metal catalysts; (iii) folding

Twisted Bilayer Graphene: Moiré with a Twist

Nano Letters, 2016
A multiscale model is developed to predict the equilibrium structure of twisted bilayer graphene (tBLG). Two distinct, modified Moiré structures are observed. The breathing mode, stable at large twist angle, has small amplitude (opposite sign) buckling of the two layers.

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.
