[20a-225B-8] Mid-infrared surface phonon polaritons probed with scattering-type scanning near-field optical microscopy
Keywords:Surface phonon polariton, Phase change material, SNOM
In this work, we observed the mid-infrared surface phonon polaritons excited on a phase change material deposited on SiC. Scattering-type SNOM visualizes their field distributions and SPhP confinement in planar cavities beyond the diffraction limit.
