Subsequent anodization leads to formation of a Si-based anodic aluminum oxide (AAO) template (AAO/Au/Si structure) with ordered nanopores. This kind of template has unique electrodeposition properties and can bond well with the deposited materials. The anodic process of the Al/Au/Si structure was investigated in detail by in situ monitoring the current-time curve. As an application, CdS nanowires were fabricated on the silicon substrate using this kind of AAO templates. Light-emitting property from the CdS nanowires was observed. This kind of Si-based light-emitting nanowires are expected to have practical applications in optoelectronic integration. © 2002 Published by Elsevier Science Ltd. 关键词: Thin films;Gold;Silicon;Surface structure;Anodic oxidation;Nanostructured materials;Porosity;Evaporation;Electrodeposition;Optical properties;Light emitting diodes;Integrated optoelectronics;Substrates;Nanowires;Electron beam evaporations
