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 phonon…

Excitonic and magnetic phases in doped WTe monolayers: a Hartree-Fock approach
Guillermo Parra-Martínez, Daniel Muñoz-Segovia, Héctor Ochoa +1
Transport and local spectroscopy measurements have revealed that monolayers of tungsten ditelluride (-WTe) display a quantum spin Hall effect and an excitonic gap at neutr…
