Template-based synthesis of nanorod, nanowire, and nanotube arrays

This review introduces and summarizes the fundamentals and various technical approaches developed for the template-based synthesis of nanorod, nanowire and nanotube arrays. After a brief introduction to various concepts for the growth of nanorods, nanowires and nanobelts, attention will be focused mainly on the most widely used and well established techniques for the template-based growth of nanorod arrays: electrochemical deposition, electrophoretic deposition, filling of templates by capillary force and centrifugation, and chemical conversion. In each section, relevant fundamentals will be first introduced, followed with examples to illustrate the specific details of each technique.
