Raman spectra of twisted bilayer graphene close to the magic angle

Tiago C. Barbosa, Andreij C. Gadelha, Douglas A. A. Ohlberg +5

In this work, we study the Raman spectra of twisted bilayer graphene samples as a function of their twist-angles ($\theta$), ranging from 0.03${}^{\circ }$ to 3.40${}^{\circ }$, where local $\theta$ a…
