Abstract

SiC-Shell nanostructures were fabricated by replicating ZnO nano-objects to produce hollow nanostructures of desired shape. The SiC hollow nanostructures were used as nanoreactors, and molecular transporters. SiC is an important semiconductor in the fabrication of electronic devices operated at high temperature, power, and frequency and in harsh environments. The synthesis strategy of SiC hollow nanostructures involved two steps as in the first step a SiC layer was deposited on the surface of the ZnO nanostructure templates to form ZnO-SiC core-shell nanostructures through plasma-enhanced chemical vapor deposition (PECVD). In the second step, the ZnO-SiC core-shell nanostructures were added to a dilute HCl solution to remove the ZnO nanostructure templates. Transmission electron microscopy (TEM) was used to reveal the shell structure of the replicated nanostructures.
