Carbothermal reduction vapor phase transport growth of ZnO nanostructures: Effects of various carbon sources

Abstract: Defects in interfacial layers and their role in the growth of ZnO nanorods by metallorganic chemical vapor deposition Appl.ZnO nanostructures were grown via carbothermal reduction vapor phase transport with carbon black, activated carbon, and graphite powders. Nanostructures can be grown at significantly lower temperatures with carbon black and activated carbon, although with different morphologies compared to graphite. The surface areas of the carbon black and activated carbon are higher than those of graphit… Show more

“…ZnO nanomaterials are among the most important one-dimensional (1-D) nanomaterials due to their semiconducting, piezoelectric, and biocompatible properties. ZnO nanomaterials have been found to have a wide range of morphologies such as nanorods, nanotubes, nanobelts and nanorings and the shape and size of such nanostructures play an important role for the performance of the devices [3,4]. There has also been a great deal of attention in ZnO material because of its prospects in optoelectronic applications including chemical sensors, solar cells and optoelectronic devices owing to its direct wide band gap of 3.37 eV at room temperature with a large exciton binding energy (60 meV) [5].…”

“…6 ZnO nanostructure growth via VPT involves four stages: generation of source species, transport of source species to the substrate, impingement of material onto the substrate (i.e condensation and nucleation) and incorporation of material into a nanostructure. This paper focuses on the production of the source species and the impingement of the material onto the substrate for ZnO nanostructure growth using Zn vapour generation via carbothermal reduction (CTR) of ZnO powders.…”
