a Schematic representation of the process from coating the catalyst precursor to the electrodeposition of silver on SWNT arrays. b SEM image of the superlong well-oriented SWNT arrays after Ag deposition. The SWNT without Ag deposition is indicated by the black arrow. c and d are typical Raman spectra (type A,B) from isolated individual SWNTs using two different laser excitations 2.41 and 1.96 eV
