摘要： 用电化学沉积方法，在有机介孔模板上制备出直径为90 nm的金纳米线.透射电子显微镜（TEM）分析结果表明，纳米线表面光滑并呈单晶结构.去除有机模板的金纳米线阵列用扫描电子显微镜（SEM）测试，纳米线顶端呈平台状，直径分布均一.我们利用原子力显微镜（AFM）测量了金纳米线阵列的微观结构，得到与SEM相一致的结果.在大气和室温条件下，用导电AFM针尖在接触模式下测量了单根纳米线的轴向I－V特性曲线，其结果为金属性.

关键词: 金纳米线, AFM, I－V特性曲线

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.
