New paper 'Lifetime and Molecular Coupling in Surface Phonon Polariton Resonators'
Friday, May 10, 2024
In this paper, we uncover how the properties of SPhP modes offer some challenges for surface-enhanced sensors. To do so we develop numerical models for understanding both the lifetime and frequency of resonances in silicon carbide resonators. Our results reveal a comparatively narrow range in the center of the Reststrahlen band offers the best candidate spectral range for enhanced sensing.
