By integrating together the VO2’s unique near room-temperature (RT) semiconductor-metal (S-M) phase transition with a thin layer silver’s (Ag) plasmonic properties, VO2/Ag multilayers could present a much enhanced optical transmission change when increasing the temperature from RT to over VO2’s S-M phase transition temperature. Changing VO2 and Ag layer thicknesses can also significantly tune their transmission and absorption properties, which could lead to a few useful designs in optoelectronic and energy-saving industries.
