Abstract

The M1 form of vanadium dioxide, which exhibits a reversible insulator-metal transition above room temperature, has been incorporated into nanoscale heterostructures through solution-phase epitaxial growth on the tips of rutile TiO<subscript>2</subscript> nanorods. Four distinct classes of VO<subscript>2</subscript>-TiO<subscript>2</subscript>-VO<subscript>2</subscript> nanorod heterostructures are accessible by modulating the growth conditions. Each type of VO<subscript>2</subscript>-TiO<subscript>2</subscript>-VO<subscript>2</subscript> nanostructure has a different insulator-metal transition temperature that depends on the VO<subscript>2</subscript> domain sizes and the TiO<subscript>2</subscript>-VO<subscript>2</subscript> interfacial strain characteristics.
