We prepared the ordered porous alumina membrane by a two-step anodization method in oxalic or sulfuric acids, which is a self-ordered hexagonal array of cells with an adjustable pore diameter of 20-150nm and a different pore structures (i.e. Y-branched, dendriform, toothed and torous ones). Furthermore, the template-electrodeposition, vapor-catalytic growth, and controlled chemical etching were developed for well-aligned carbon nanotubes and oxide nanopillars with adjustable diameter, Al2O3-AlN one-dimensional heterojunction, Y-junction and dendriform metal nanowires, as well as Y-junction, and torous carbon nanotubes. The resultant one-dimensional junctions were characterized by XRD, SEM, TEM,HRTEM, and STM, and the field emission of the well-aligned carbon nanotubes and the luminescence of ZnO nanopillar array have also been mearsured.
