Abstract

Ordered Al2O3 nanowire arrays embedded in the nanochannels of anodic alumina membranes (AAMs) were synthesized by electrodepostion at room temperature. Our synthetic route yielded large quantities of Al2O3 nanowires of uniform size and shape that are ~40 µm long with diameters of 70 nm. The Al2O3 nanowire structures were characterized by scanning and transmission electron microscopies, high-resolution transmission electron microscopy, energy dispersive spectroscopy and X-ray photoelectron spectroscopy.
