Temperature-agile and structure-tunable optical properties of VO2/Ag thin films

Combination of vanadium dioxide’s (VO2) semiconductor-to-metallic phase transition and Ag’s plasmonic properties actually results in very interesting optical reflection, transmission, and absorption behaviors. A double thin layer VO2/Ag presents a significant change in transmission when increasing the temperature from room temperature to over VO2’s phase transition temperature of ~68oC. Changing the layer thickness can also largely tune the optical properties, which could lead to a few potential applications in energy-saving and optoelectronic industries.
