Abstract

Abstract: Colloidal Au nano-crystalline in aqueous phase was synthesized and analyzed by means of TEM (about 29 nm). When several drops of this solution were dropped onto a clean silicon wafer(110), a snowflake or dendrite fractal structure formed with water vaporized under natural circumstances. Such structures were investigated by virtue of optical microscope and AFM. The mechanisms of Au nano-crystalline fractal growth on silicon surface were discussed.

Key words: Au nano-crystalline, silicon surface, fractal
