我们在100℃下用原子层沉积(ALD)的方法证明了ZnO-Al{sub2}O{sub3}核壳纳米线的晶态结构。这种核壳结构在氧化锌场效应晶体管的制备中具有潜在的应用前景。将氧化锌晶核溶解后，得到了形状明确、刚性好、结晶性好的纳米晶Al{sub2}O{sub3}。纳米线氧化锌纳米结构已经被氧化铝壳复制。这是制造任何所需物体的核壳或壳/中空纳米结构的最有效技术之一。Al{sub2}O{sub3}壳层纳米结构在空间受限纳米反应器、药物输送、纳米流体通道和光传输等方面具有潜在的应用前景。
We have demonstrated the crystalline ZnO-Al{sub 2}O{sub 3} core-shell nanowire structure by atomic layer deposition (ALD) at a temperature 100 deg. C. The core-shell structure could have potential applications in the fabrication of ZnO field effect transistor. After dissolving the ZnO core, shape defined, rigid and robust crystalline Al{sub 2}O{sub 3} shelled nanostructures have been fabricated. Nanowire ZnO nanostructures have been replicated by alumina shell. This is one of the most effective techniques for producing core-shell or shell/hollowed nanostructures of any desired objects. The Al{sub 2}O{sub 3} shelled nanostructures could have potential applications as space confined nanoreactors, drug delivery, nanofluidic channels and optical transmitting.
