[交流] 关于一系列金属氧化物的一篇综述（2006年的）

Abstract
Recent advances in the field of nanotechnology have led to the synthesis and characterization of an assortment of
quasi-one-dimensional (Q1D) structures, such as nanowires, nanoneedles, nanobelts and nanotubes. These fascinating
materials exhibit novel physical properties owing to their unique geometry with high aspect ratio. They are the
potential building blocks for a wide range of nanoscale electronics, optoelectronics, magnetoelectronics, and sensing
devices. Many techniques have been developed to grow these nanostructures with various compositions. Parallel to the
success with group IV and groups III–V compounds semiconductor nanostructures, semiconducting metal oxide
materials with typically wide band gaps are attracting increasing attention.
This article provides a comprehensive review of the state-of-the-art research activities that focus on the Q1D
metal oxide systems and their physical property characterizations. It begins with the synthetic mechanisms and
methods that have been exploited to form these structures. A range of remarkable characteristics are then presented,
organized into sections covering a number of metal oxides, such as ZnO, In2O3, SnO2, Ga2 O3, and TiO2, etc.,
describing their electrical, optical, magnetic, mechanical and chemical sensing properties. These studies constitute the
basis for developing versatile applications based on metal oxide Q1D systems, and the current progress in device
development will be highlighted.
