Enhanced heat transfer across h-BN interfaces via coupling between hot electrons and phonon-polaritons
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…
