Aligned small alpha-SiC nanorods on beta-SiC particles grown in an arc-discharge

摘要

Aligned alpha -SiC nanorods, several nanometers in diameter and with lengths up to 200 nm, were grown on the facets of simultaneously formed beta -SiC particles by using an SiC rod as the anode to are-discharge in a helium atmosphere. SEM, TEM and XRD were employed to characterize the prepared nanostructures. The small alpha -SiC nanorods exhibit excellent elastic deformation ability and have a strong bond to the beta -SiC substrate. The possible growth mechanism of the nanostructures is discussed.
