Enhanced Dielectric Properties and Excellent Microwave Absorption of SiC Powders Driven with NiO Nanorings

Abstract

Enhancement of the dielectric properties of SiC is achieved by growing the NiO nanorings on the surface of SiC. The SiC assembled with NiO nanorings exhibits highly enhanced dielectric properties and strong microwave absorption due to the hopping charge induced by the NiO nanorings.
