Confined surface waves in layered dielectric materials

Confined surface waves in layered dielectric materials
Confined surface waves in layered dielectric materials
We demonstrate deep subwavelength confinement of surface phonon-polaritons in silicon carbide by capping the crystal with nanometric layers of MoS2. Near-field nano-imaging shows 85 time surface wave confinement in comparison with free-space wavelength of 11.15 micrometers.

Abstract

We demonstrate deep subwavelength confinement of surface phonon-polaritons in silicon carbide by capping the crystal with nanometric layers of MoS2. Near-field nano-imaging shows 85 time surface wave confinement in comparison with free-space wavelength of 11.15 micrometers.
