Origin of van Hove singularities in twisted bilayer graphene

In this work, we present a resonance Raman spectroscopy study of more than 100 samples of twisted bilayer graphene (TBG) with a continuous distribution of twisting angles from 0° to 30°, using three different laser excitation energies (1.96, 2.33 and 2.54eV). From the Raman images of all investigate...
