Sb2S3 is a chalcogenide material with a heat-controlled transition from amorphous to crystalline phase. Combined with significant changes in optical properties during the transition, it is an extremely interesting and applicable material for applied IR optics. In this talk, we present nanofabricated resonant Sb2S3 pillars, showing how methodically designed metasurfaces with these structures can exhibit a wide range of optical properties across the phase change. Furthermore, we show a tunable ability to control these metasurfaces with intentional design.
Investigation into the interface formed between Sb2Te3/Ni80Fe20 heterostructures – this is studied using temperature dependent magnetometry, scanning transmission electron microscopy, ferromagnetic resonance, and theoretical support.
