摘要：

Coaxial nanowires, with about 45 nm in diameter and about 15 mu m in length, have been synthesized by reaction of silicon dioxide nanoparticles with active carbon at 1450 degrees C in flowing nitrogen atmosphere. Their structures consist of an alpha-phase silicon nitride core, an amorphous silicon and a silicon dioxide outer shell, similar to those of coaxial nanocables. The formation mechanism of the coaxial nanowires is discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
