Observation of well-defined Kohn-anomaly in high-quality graphene devices at room temperature
Andreij C. Gadelha, Rafael Nadas, Tiago C. Barbosa +5
Due to its ultra-thin nature, the study of graphene quantum optoelectronics, like gate-dependent graphene Raman properties, is obscured by interactions with substrates and surround…

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 (), ranging from 0.03 to 3.40, where local a…
