Abstract

original image

Ultrahigh pore density nanoporous films with cylindrical pores that are perpendicular to the substrate and parallel to each other have been fabricated, and the Al nanocylinders successfully removed (see Figure). The template-assisted growth of ultrahigh density Ni nanowire arrays have also been achieved by direct-current electrodeposition with nearly 100 % of the pores filled with Ni.
