Abstract

Electroplating of ZnO nanowires was conducted using gold embedded anodized aluminum oxide (AAO) films on Si substrates. For electroplating, insulating layers at the bottom of AAO nanohole structures need to be removed. After electroplating, hexagonal structure of vertical ZnO nanowires was observed, however, they were broken and lied down by thermal annealing process. Photoluminescence (PL) spectra were investigated and that of post annealed ZnO nanowires indicates that nitrogen atoms were incorporated as acceptor.
