Abstract

This paper reports the synthesis and characterization of flower-shaped gold (Au) crystals. The Au particles are synthesized via a facile route by dipping the freshly anodic etched porous silicon (Si) into HAuCl ₄· 3H ₂O aqueous solution. The shape and size of Au clusters can be controlled by adjusting the concentration of HAuCl ₄ and duration of the reaction. The Au nanoparticles are in-situ formed and this process/reaction is accompanied by the oxidation of porous Si. This Au-coated porous Si electrode is confirmed to be a metalinsulatorsemiconductor device by the currentvoltage and the capacitancevoltage plots. Our work provides a very simple and convenient route to synthesize Au crystals on anodic etched porous Si.
