Controllable growth of InN nanostructures (Invited Review)

In this review, we take a survey of synthesis approaches and growth mechanisms of one-dimensional (1D) InN<br />nanostructures in a controlled manner. InN nanostructures with hexagonal wurtzite single-crystalline structures<br />using chemical vapor deposition (CVD) technique are discussed herein. Firstly, we attempt to overview novel<br />growth approaches for a controllable synthesis of InN nanostructures, focusing on vapor&ndash;liquid&ndash;solid (VLS)<br />and vapor&ndash;solid (VS) mechanisms with different starting materials. In second section, we address the factors<br />influencing InN growth directions, including 0001 , 10&macr;10 and 0&macr;111 . Finally, we present a systematically<br />analysis of intriguing morphologies such as nanowires, nano-cones, and crystallites with a great yield.<br />KEYWORDS: Vapor&ndash;Liquid&ndash;Solid Growth, Nanostructure, Surface Adatoms Diffusion
