Metastable Vanadium Dioxide Nanobelts: Hydrothermal Synthesis, Electrical Transport, and Magnetic Properties

Abstract

Made-to-measure nanobelts: Metastable vanadium dioxide single-crystal nanobelts (see picture) were prepared by a hydrothermal reduction method by treating an ammonium metavanadate solution with formic acid. The morphology of the belts could be adjusted by varying the reaction parameters, such as temperature, pH, and reaction time.
