VO2 undergoes metal-insulator transition (MIT) at the transition temperature (τc) of 68 °C, accompanied by a sharp optical response change. A unique Au/VO2 half-sphere core-shell structure is fabricated to study the temperature-dependent plasmonic effects and the thermochromic response for smart win...
