Abstract :
Based on diffusion-limited aggregation process, a convenient nanotechnique is demonstrated to obtain fractal silver on conductive substrate. SEM and HRTEM images show the morphology nanostructure can be well controlled by the electrochemical process. The as-fabricated silver nanostructure exhibited SERS enhancement factor approximately 105. The study can help us to combine nano-metals and nano-particles for the application in advanced nano devices.
