Enhanced heat transfer across h-BN interfaces via coupling between hot electrons and phonon-polaritons
BySarah Ross January 31, 2025March 1, 2025

Patrick E. HopkinsUniversity of Virginia – Charlottesville, Virginia, USA_______________________________________ Thermal transport across solid-solid interfaces is vital for advanced electronic and photonic applications, yet conventional conduction pathways often restrict performance. In polar crystals, hybridized vibrational modes called phonon-polaritons offer a promising avenue to overcome the limitations of intrinsic phonon heat conduction. Our work demonstrates that volume-confined…

Landau-Phonon Polaritons in Graphene/hBN Heterostructures: A Nanoscopy Perspective
BySarah Ross January 29, 2025March 1, 2025

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,…

Twisted hBN as a new platform for moiré engineering
BySarah Ross January 3, 2025March 1, 2025

Xiaoqin Elaine LiUniversity of Texas at Austin – Austin, Texas USA_______________________________________ Moiré superlattices are typically created by stacking and twisting two functional layers, such as graphene and transition metal dichalcogenides (TMDs). This process often results in simultaneous changes in electronic and photonic properties as a function of the twist angle, which can impose undesirable constraints….
