Yj. Xing et al., Solid-liquid-solid (SLS) growth of coaxial nanocables: silicon carbide sheathed with silicon oxide, CHEM P LETT, 345(1-2), 2001, pp. 29-32
Coaxial silicon carbide-silicon oxide nanocables on silicon substrates were
synthesized from the ternary system of SiNi-C at 950 degreesC under Ar/H-2
atmosphere. The nanocables consist of a hexagonal crystalline SiC core and
a surface layer of amorphous silicon oxide, which have an average diameter
of similar to 50 nm and a length of several tens of microns. The microstru
cture and composition of the nanocables were characterized using high-resol
ution transmission electron microscope (HREM), and electron energy loss spe
ctroscopy (EELS), and the growth mechanism of the nanocables was explained
under the framework of a solid-liquid-solid (SLS) mechanism. (C) 2001 Elsev
