Synthesis of SiC/SiO₂ core-shell nanowires with good optical properties on Ni/SiO₂/Si substrate via ferrocene pyrolysis at low temperature.

ABSTRACT: In this study, the high-density SiC/SiO₂ core-shell nanowires were synthesized on the nickel coated SiO₂ (100 nm)/Si substrate by chemical vapor deposition (CVD) method with ferrocene precursor at temperature 1000 °C compared to previous studies (1300-1600 °C). The present work provides an efficient strategy for the production of SiC/SiO₂ nanowires with uniform morphology and good optical properties, where the Ni layer plays important roles for this fabrication at low temperature which reduces the decomposition temperature of hydrocarbon gases and improves the growth quality of SiC nanowires. The as-synthesized SiC/SiO₂ nanowires consist of single crystal 3C structures as well as 3C structures with defects along [111] direction. In the photolumin
