Refit Silver Nanostructures Using a Convergent Electron Beam

Using a superionic conductor AgI thin film and a direct current electric field, we synthesize silver nanowires in diameter of about 100nm. In order to refit the prepared nanowires, the samples are irradiated by a convergent electron beam (200kV) inside a transmission electron microscope to prepare new small silver nanostructures. The new nanostructures are investigated in situ by high-resolution transmission electron microscope. This electron-induced crystal growth method is useful for technical applications in fabrication of nanodevices.
