Deposition of carbon nanotubes on si nanowires by chemical vapor deposition
... not be formed very well on the surface of nanowires because of both the volume change of the nanowires and breaking of the carbon network sheathed on the nanowires. When the substrate temperature ... relatively high (b1100°C), a mixture of graphitic carbon and SiC nanowires was formed because of both the carbonization of the nanowires and the fast carbon deposition to form the...
