Ultrathin nanosheets of half-metallic monoclinic vanadium dioxide with a thermally induced phase transition

Abstract

Only the half of it: A modified intercalation-deintercalation strategy that takes advantage of the characteristic thermally induced phase transition of monoclinic VO2 has been developed for the preparation of ultrathin VO2 nanosheets. The resultant nanosheets exhibit half-metallic character and a temperature-dependent phase transition. The half-metallicity could lead to applications in spintronic nanodevices.
