Fusing Light With Heat: Polaritons for Nanoscale Thermal Transport & Sensing
Online Presentations | 07 Oct 2021 | Contributor(s):: Thomas Beechem
Light exhibits a wave nature. Phonons do too. Within the infrared portion of the spectrum, these differing “waves” can interact to form hybrid energy carriers called polaritons. Polaritons, in turn, provide fundamental advantages for optical functionality and...
