Phason-driven temperature-dependent transport in moiré graphene
Alex Boschi, Alejandro Ramos-Alonso, Vaidotas Mišeikis +9
The electronic and vibrational properties of 2D materials are dramatically altered by the formation of a moiré superlattice. The lowest-energy phonon modes of the superlattice are…

Raman scattering from moiré phonons
Vitor Dantas, Héctor Ochoa, Rafael M. Fernandes +1
We develop a theoretical framework for probing moiré phonon modes using Raman spectroscopy, and illustrate it with the example of twisted bilayer graphene (TBG). These moiré phon…
