摘　　要：采用简单的溶胶-凝胶方法在多孔阳极氧化铝模板(AAM)的微孔中制备了高度有序的SnO2纳米线阵列。XRD,SEM和TEM对样品进行了结构和形貌的表征,结果表明,高度有序的SnO2纳米线具有四方相的多晶结构,纳米线连续均匀;并对SnO2纳米线阵列的生长机理进行了探讨;最后用聚焦离子束沉积设备制作了单根SnO2纳米线器件。Highly ordered SnO2 nanowire arrays embedded in anodic alumina membranes（AAM） have been successfully fabricated by simple Sol -gel method, first SnO2 colloidal suspensions being filled in the pores of AAM ,then annealed at 600℃ for 10h. SEM and TEM images show that SnO2 nanowires are dense, continuous, uniform diameter and arranged parallelly to another; XRD and SAED analysis together indicate SnO2 nanowires crystallize with a polycrystalline tetragonal structure;then the growth mechanism of SnO2 nanowire arrays is discussed. In the end, nanodevice of a single SnO2 nanowire between two pt leads is fabricated by focused ion beam deposition （FIB）.
