With the development of nanoscience and nanotechnology, metal/silicon composite nanosystems have aroused much attention and might play key roles in fabricating silicon-based nanodevice in future. Researches have indicated that the process of the immersion plating of metals on PS highly depends upon the morphology and chemical status of PS surface, which implies that site-selective deposition of metals might be realized through surface treatment. This would be essential for the fabrication of metal/PS with p...
