Surface phonon polariton,Phonon,Heat transfer

Surface phonon-polaritons propagate along the surface of polar dielectric materials and could be heat carriers capable of remarkably enhancing the thermal performance of micro- and nanoscale devices. We experimentally observe the dominant heat contribution of SPhPs in SiN nanofilms
