ZnO nanorods and thin films were synthesized on Si(100) substrates at a low temperature by controlling the ZnO seed formation in an aqueous solution process. Vertically well-aligned ZnO nanorods with a single-crystalline hexagonal structure and c-axis growth orientation were obtained despite having a different crystal structure than a large lattice mismatch with the Si(100) substrate. In addition, the authors suggest that the lateral growth of ZnO nanorods causes them to merge together into ZnO thin films during growth into the aqueous solution. It is also suggested that the significant blueshift of the main emission band in the photoluminescence spectrum obtained from the nanorod sample at 10 K can be mainly attributed to Burstein-Moss effects in the ZnO nanorods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
