Controlled growth and electrical properties of heterojunctions of carbon nanotubes and silicon nanowires
Article Abstract:
Nanometre-scale electronic structures provide a link between molecular and solid state physics and can reach higher device densities than conventional semiconductor technology. Small devices can be made by joining two nanotubes or nanowires to create metal-semiconductor junctions, but nanotube junction structures have not been explicitly observed. Controlled, catalytic growth of metal-semiconductor junctions between carbon nanotubes and silicon nanowires are reported, and are shown to exhibit reproducible rectifying behavior.

Generalized syntheses of large-por mesoporous metal oxides with semicrystalline frameworks
Article Abstract:
A simple and flexible procedure to synthesis thermally stable, order large-pore mesoporous metal oxides is reported. Amphiphilic poly(alkylene oxide) block copolymers were used as structure-directing agents. The mesoporous oxides contained nanocrystalline domains in the comparatively thick amorphous walls, formed via a combination of block copolymer self-assembly and complexation of the inorganic species.

Single-crystal gallium nitride nanotubes
Article Abstract:
An epitaxial casting approach for the synthesis of single-crystal GaN nanotubes with inner diameters of 30-200nm and wall thickness of 5-50 nm is presented. For the epitaxial overgrowth of thin GaN layers in a chemical vapour deposition system, hexagonal ZnO nanowires are used as templates.
