Abstract: Gold nanowires with 90 nm diameter were prepared by electrodeposition on polycarbonate membrane template. Transmission electron microscope(TEM)results indicated that the surfaces of nanowires were smooth and exhibited single crystal structure. Scanning electron microscopy showed that these gold nanowires had flat roofs and were distributed uniformly on the substrate. The array microstructure of nanowires determined by atomic force microscope(AFM) was consistent with scanning electron microscope(SEM)results. The I-V characteristics of individual nanowire by AFM revealed metallic characteristics with a conductive tip operating in contact mode at room temperature in air.

Key words: Gold nanowires, AFM, I-V characteristics curve
