Self-catalysis induced three-dimensional SiOx nanostructures

Abstract

Three-dimensional SiOx nanostructures with various shapes have been prepared by chemical vapor deposition. The sunflower-like SiOx nanostructures provide a chance to probe the growth process. A typical Ga-assisted vapor–liquid–solid (VLS) model is responsible for the incipient SiOx nanostructures, while the growth of their branches is governed by a SiOx self-catalysis mechanism. Elemental analysis unveils the initial stage and evolution of SiOx nanostructure formation. The optical properties of SiOx nanostructures are also investigated.
