title: Growth of pagoda-topped tetragonal copper nanopillar arrays.
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.
