Vertically Aligned Zn₂SiO₄ Nanotube/ZnO Nanowire Heterojunction Arrays

Up the junction: An approach for fabricating Zn2SiO4 nanotube/ZnO nanowire heterojunction arrays (see picture) is introduced by using ZnO-nanowire arrays as a template. The technique, which is based on a plasma-enhanced chemical vapor deposition process, reveals a novel, low-cost, and efficient method for aligning nanotube/nanowire heterojunctions, which could be useful for fabricating novel nanodevices.
