Calculation of Nanowire Growth Activation Energy

Abstract:

Two-step preparation technology was used to prepare anodic aluminum oxide (AAO) templates. Then deposit Ni nanowire arrays in nanopores of AAO templates by direct current deposition. TEM spectra of nanowires show that the length of nanowires is uniform and that the shape of nanowires is the same with that of nanopores. Finally, reaction activation energy of Ni growing in nanopores was calculated by experimental data. Results show that Ni growing in the smaller nanopores is much easier than in the bigger nanopores.
