The back cover illustrates catalytic growth of silicon nanowires in a nanoporous alumina template as reported by D. Buttard et al. (p. 1606). The Vapor–Liquid–Solid mechanism is a well-known method to grow nanowires and nanotubes. The growth takes place with a gold catalyst and vapor of silane (SiH4) in a Chemical Vapor Deposition reactor. Depicted is a typical Scanning Electron Microscopy cross section observation of silicon nanowire growth directly from a <100> silicon substrate using a nanoporous alumina template. The silicon nanowire is guided in the <100> direction along the cylindrical structure. The pore walls also form an electrical insulator and give good mechanical and thermal properties to the whole structure. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
