Controllable assembly of the Au nanowire in micro/nano structure by templateless electro-deposition

A novel templateless electrochemical deposition method for controllable assembly of Au nanowire in micro/nano structure was proposed. This method could assemble various nano-patterns (individual, array, network etc.) by utilizing different parameters and characterizes simple-apparatus, low-cost and innoxious-electrolyte. The characterization results prove the fabricated Au nanowires were single-crystal structure with tens of nanometers diameter. The measurement results of the electrical characteristics demonstrate that the Au nanowire has good electric conductivity (the resistivity is 2.64 × 10^-7 ¿·m). It had the application potentials in micro/nano interconnection, bio/chemical sensors etc..
