Landau-Phonon Polaritons in Graphene/hBN Heterostructures: A Nanoscopy Perspective
Mengkyn LiuStony Brook University – Stony Brook, New York, USA_______________________________________ Hexagonal boron nitride (hBN) serves as a versatile platform for hosting polaritonic phenomena in low-dimensional materials. We report on a novel type of polaritons—Landauphonon polaritons (LPPs)—emerging from the hybridization of Dirac magnetoexciton modes in graphene with waveguide phonon polariton modes of hBN. Using infrared magneto-nanoscopy,…
