Description
Summary:Single-crystalline vanadium dioxide (VO2) nanostructures are of great interest because of their single-domain metal-to-insulator transition. In this paper, singlecrystalline W-doped VO2 nanobeams are synthesized for optical and electrical applications. As a result of differences in the polarization of the beams along their transverse and longitudinal axes, dual-surface plasmon resonance peaks at 1344 and 619 nm are generated, resulting in an increase in the solar modulating abilities of the VO2 nanobeams. The conductivity of the single-crystalline W-doped VO2 nanobeams changes by three to four orders of magnitude at the transition temperature, which is of great importance for electrical applications.
