Formation of Surface Silver Nano-network Structures through Hot Electron Regulated Diffusion-limited Aggregation

Abstract A surface Ag nano-network pattern is formed by first depositing Ag nanoparticles (NPs) on a conductive template, which has a certain defect structure, and then illuminating the Ag NPs with ultraviolet (UV) light in a moist environment. Such an Ag nano-network pattern consists of multiple co...
