在准一维极性纳米结构中，长轴和极性轴的相对取向将决定纳米结构的极性如何被用于应用。本文采用分子束外延的方法制备了极轴垂直于生长轴的准一维ZnO纳米结构（特别是纳米带）。我们证明了生长温度对纳米结构形态的控制。我们的工作代表了未来偏振工程氧化物异质结构嵌入准一维纳米器件发展的关键里程碑。(C) 2017年作者。Elsevier B.V.出版
In quasi-one-dimensional polar nanostructures the relative orientation of the long and polar axes will determine how the polarity of the nanostructure may be exploited for applications. Here we present the growth by molecular-beam epitaxy of quasi-1d ZnO nanostructures (specifically nanobelts) with the polar axis perpendicular to the growth axis. We demonstrate the control of nanostructure morphology by growth temperature. Our work represents a key milestone towards the development of future polarization-engineered oxide heterostructures embedded in quasi-1d nanodevices. (C) 2017 The Authors. Published by Elsevier B.V.
