Research paperTheoreticalComputed RamanEmergent intersubband-plasmon-polaritons of Dirac electrons under one-dimensional superlatticesMinwoo Jung, Gennady ShvetsarXiv·2022·10.48550/arxiv.2203.13844·arXiv:2203.13844AbstractArtificial one-dimensional superlattice potentials in monolayer graphene can deform Dirac dispersion into flat subbands and produce emergent intersubband plasmon-polariton responses. The paper studies a double-gated hBN-encapsulated graphene device with a patterned metagate and backgate, uses electrostatic simulations to obtain spatially modulated carrier density and superlattice potentials, and calculates the resulting subband structure and hybrid intersubband-plasmon-polariton dispersions.Read more
