Fabrication and photoelectrical behavior of macroscopic-long silver nanowire ribbon/bulk metal contact.
Macroscopic-long silver nanowire ribbon including thousands of parallel aligned silver nanowires was prepared on a bare optical fiber surface in the solid phase using a solid state ionics method. Their structural characters were described at different spatial scales. The photoelectrical behavior between two contact interfaces of the ribbon and bulk metal (Ag or Ni) electrodes was explored using a local illumination by a 532 nm laser beam. Photoinduced currents were found dramatically depend on the laser spot position relative to the contact interface. In addition, the magnitudes of photoinduced current were different from been contact with Ag electrodes to Ni electrodes.
