Inside Front Cover: Self-Assembly of SiO2 Nanowires and Si Microwires into Hierarchical Heterostructures on a Large Scale (Adv. Mater. 8/2005)
The inside cover shows a scanning electron micrograph of a novel hierarchical heterostructures, as reported by Hu and co-workers on p. 971. The heterostructures are formed from Si core microwires covered by dense, aligned SiO2 nanowires, thus forming multiple junctions to the cores. The inset shows a schematic of the Sn-catalyzed vapor–liquid–solid growth mechanism. These materials are envisaged to become important for optical fibers, low-dimensional waveguides, scanning near-field optical microscopes and high-bandwidth optical signal processing devices.
