Growth of ZnO nanowires on modified well-aligned carbon nanotube arrays.

Single-crystal ZnO nanowires were successfully grown on modified well-aligned carbon nanotube (CNT) arrays by a hydrothermal process. The pre-deposited ZnO grains on the CNTs served as the nucleation sites for the growth of ZnO nanowires. The attached growth of ZnO nanowires on the well-aligned CNT arrays formed a 3D configuration. The 3D hybrid nanostructured material could find application in sensors and other electronic or optoelectronic devices.
