摘要：

Hierarchical single-crystalline beta-SiC nanoarchitectures have been successfully synthesized using a catalyst-assisted thermochemical process. Their morphology and structure were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Studies found that the central nanowires have diameters of similar to 10-20 nm and the branched nanoplatelets have thicknesses of 5-10 nm. Field emission measurements showed that the hierarchical beta-SiC nanoarchitectures have a turn-on field of similar to 12 V/mu m.
