Abstract
By integrating together VO2’s unique near-room-temperature (RT) semiconductor–metal (S–M) phase transition with a thin silver (Ag) layer’s 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.
