A Novel Heteronanostracture System: Hierarchical W Nanothorn Arrays on WO_3 Nanowhiskers

摘要

The assembly of ID nanostructures in the fabrication of nanoelectronic and nanophotonic devices is currently attracting significant attention. In particular, semiconductor and metal nanowires or nanorods are considered to be important building blocks in the fabrication of future nanodevices. Various types of nanowire heterostructures have been reported, including core/shell and core/multishell nanocable structures, coaxial nanowire heterojunctions, 31 epitaxial nanorod heterostructures, and hierarchical heterostructures. Hierarchical heterostructures are useful for the realization of 3D multicomponent functional nanodevices because the cores and branches of these nanostructures are composed of different materials.
