Abstract

Growth of arrays of pagoda-topped tetragonal Cu nanopillar (length 1- 6 mum; width 150 +/- 25 nm) with {100} side faces on Au/glass is achieved by a simple electrochemical reduction of CuCl(2)(aq) by Al(s) in aqueous dodecyltrimethylammonium chloride. Field-emission measurement shows that the Cu nanopillars can emit electrons (10 muA cm(-2)) at a turn-on field of 12.4 V mum(-1) with a calculated field enhancement factor of 713.

摘要

在 Au/玻璃上，通过 Al(s) 在十二烷基三甲基氯化铵水溶液中电化学还原 CuCl2(aq)，实现了具有{100}面的宝塔形四方 Cu 纳米柱（长度 1-6 微米；宽度 150 +/- 25 纳米）的阵列生长。场发射测量表明，Cu 纳米柱在 12.4 V mum(-1)的开启电场下可以发射电子（10 muA cm(-2)），计算出的场增强因子为 713。
