Abstract

A method for growing vertical ZnO nanowire arrays on arbitrary substrates using either gas-phase or solution-phase approaches is presented. A approximately 10 nm-thick layer of textured ZnO nanocrystals with their c axes normal to the substrate is formed by the decomposition of zinc acetate at 200-350 degrees C to provide nucleation sites for vertical nanowire growth. The nanorod arrays made in solution have a rod diameter, length, density, and orientation desirable for use in ordered nanorod-polymer solar cells.

摘要

本文提出了一种使用气相或溶液相方法在任意衬底上生长垂直氧化锌纳米线阵列的方法。通过在200-350摄氏度下分解醋酸锌，形成一层厚度约为10纳米、其c轴垂直于衬底的织构氧化锌纳米晶体层，为垂直纳米线生长提供成核位点。溶液中制备的纳米棒阵列具有用于有序纳米棒-聚合物太阳能电池所需的棒直径、长度、密度和取向。
