Twisted 2D layers
Twisted 2D layersare formed by stacking layers of atomically thin materials, such as graphene orTMDCs, with a relative rotational misalignment. At large twist angles, a moirésuperlattice is introduced, which can lead to spatial modulation of structuralparameters, electronic energies, and optical transitions. At smaller angles,sometimes called "magic angles," the strong electronic interactionscan lead to phenomena such as superconductivity and correlated insulatingstates. Our research focuses on investigating the exciton physics of twistedstructures, including exciton-phonon coupling, interlayer interaction, andfunctionalized twisted structures.
