AFM Study of Gold Nano wires Array Electrodeposited Under AC Lower Frequency

Abstract

Abstract: Hexagonally ordered microporous aluminum anoxic oxide(AAO) template was prepared by two-step anodization process.The thickness and diameter of the anodic alumina pore is proportional to the an-odization voltage and the second time anodization.Au/AAOmembrane was also characterized by X-ray diffraction (XRD).Gold nanowires array was prepared in AAOby a lower frequency ACelectrodeposition.The deposition rate of gold nanoparticles under the lower frequency is slower than under the higher frequency,so the membrane surface of Gold/AAOis uniform.The morphology of the nanowires array uniformly filled in hexagonally ordered pore was also monitored by atomic force microscope (AFM) after dissolution parts of alumina film.

Key words: Porous anodic aluminum oxide, Electrodeposition, N+anowires, Atomic force microscope
