Dendritic Gold Nanostructures: Fabrication and Potential Application in Nanoelectronics

Abstract

Using N, N-dimethylformamide (DMF) as electrolyte and applying a DC voltage between a pair of Au/Ti electrodes, well-defined dendritic gold nanostructures could be prepared near the surface of cathode. These nanostructures were composed of gold nanocrystals with average diameter about 10-20 nm. The configurations of the dendritic gold nanostructures resemble the diffusionlimited-aggregation (DLA) patterns. From electric measurements, the authors find that these novel dendritic nanostructures may have potential applications in nanoelectrics
