Double-resonance Raman scattering is a sensitive spectroscopic probe of the interplay between electrons and phonons in a crystal. Here, the authors unveil the signature of double-resonance intervalley scattering by acoustic phonons in two-dimensional

When two periodic two-dimensional structures are superposed, any mismatch rotation angle between the layers generates a Moiré pattern superlattice, whose size depends on the twisting angle θ. If the layers are composed by different materials, this

Twisted bilayer graphene is a fascinating system due to the possibility of tuning the electronic and optical properties by controlling the twisting angle $$\theta$$ θ between the layers. The coupling between the Dirac cones of the two graphene layer
