准一维金属氧化物纳米线在纳米器件的发展中具有重要的应用前景。锡，铟，锌氧化物的单晶纳米线的形式，通过从气相冷凝生产。此外，还制备了纵向和径向异质结。纳米线生长在受控条件下进行，并允许利用尺寸减小对气体的电响应的影响。纳米线的制备，微观结构，形态和电学特性的介绍和这些创新的结构的特点突出。(C)2009爱思唯尔有限公司版权所有。
Quasi one-dimensional nanowires of metal oxides are promising for the development of nano-devices. Sn, In, and Zn oxides were produced in form of single-crystalline nanowires through condensation from vapor phase. Furthermore longitudinal and radial heterostructures have been prepared. Nanowires growth Occurs in controlled condition and allows the exploitation of size reduction effects on the electrical response to gases. Preparation, microstructural, morphological and electrical characterizations of nanowires are presented and the peculiarities of these innovative structures are highlighted. (C) 2009 Elsevier B.V.
