Overview

Randomized trial demonstrates enhanced plasmon damping in nanocavities with ferroelectric materials, suggesting new device applications.

Key Points

This research aims to explore how ferroelectric phase transitions affect plasmon damping at metal-dielectric interfaces.
Constructed an Au/CIPS/Au nanodisk-on-mirror nanocavity utilizing CuInP2S6 ferroelectric material.
Analyzed the optical response of the nanocavity and measured plasmon damping during ferroelectric phase transitions.
Evaluated optical sensitivity to quantify performance in plasmonic applications.
Plasmonic nanocavity enhanced light-matter interactions by 37-fold in scattering compared to Au/CIPS structure.
Damping increased steeply when temperature crossed the Curie temperature, with polarization-intensity proportionality observed.
Constant baseline damping was noted, attributed to surface scattering, alongside polarization-induced damping variations.
