Twisted 2D layers

Twisted 2D layers are formed by stacking layers of atomically thin materials, such as graphene or TMDCs, with a relative rotational misalignment. At large twist angles, a moiré  superlattice is introduced, which can lead to spatial modulation of structural parameters, electronic energies, and optical transitions. At smaller angles,  sometimes called "magic angles", the strong electronic interactions  can lead to phenomena such as superconductivity and correlated insulating states. Our research focuses on investigating the exciton physics of twistedstructures, including exciton-phonon coupling, interlayer interaction, and functionalized twisted structures.
