Abstract The dielectric properties of nano Si/C/N composite powder and nano SiC powder at high frequencies have been studied. The nano Si/C/N composite powder and nano SiC powder were synthesized from hexamethyldisilazane ((Me 3 Si) 2 NH) (Me:CH 3) and SiH 4-C 2 H 2, respectively, by a laser-induced gas-phase reaction.
