SiC‐Shell Nanostructures Fabricated by Replicating ZnO Nano‐objects: A Technique for Producing Hollow Nanostructures of Desired Shape

Shelling out: A replica technique is demonstrated for fabricating hollow SiC nanostructures of any shape (see figure) as defined by templates of pregrown ZnO nanostructure templates. The technique is based on plasma-enhanced chemical vapour deposition (PECVD) at a temperature of ≈250–300 °C. The SiC-shell nanostructures have potential applications as catalysts, in drug delivery, and nanofluidics.
