采用低成本的水化学生长技术，成功地在氧化铟锡包覆的石英衬底上生长出了ZnO纳米棒阵列。利用原子力显微镜的导电尖端研究了单个纳米棒的电学特性。研究了紫外辐照对单纳米棒电导率的影响。我们观察到光电导率的持久性，最可能归因于氧化锌纳米棒中的氧空位。
Arrays of standing nanorods of ZnO were successfully grown on indium tin oxide coated quartz substrates by an inexpensive aqueous chemical growth technique. The electrical properties of individual nanorod were investigated with the conducting tip of an atomic force microscope. The effect of ultraviolet irradiation on the conductivity of single nanorods was investigated. We observed a persistency of the photoconductivity, most probably ascribable to the oxygen vacancies in ZnO nanorods.
