In this study, we used a thin-film coating with the Fabry-Perot (FP) effect to enhance emissivity contrast ({\\Delta}{\\epsilon}) between VO2 phase-change states. This coating utilizes a novel hybrid material architecture that combines VO2 with a mid- and long-wave infrared transparent chalcogenide, zinc sulfide (ZnS), as a cavity spacer layer.
