ABSTRACT
Elevated-temperature synthesis has been used to generate side-by-side biaxially structured silicon carbide-silica nanowires. The axial growth direction approaches [311] for nanowires with a high density of microtwins and is [211] for defect-free nanowires. The structure of these nanowires, their cross-sectional shape, and their structural transformation between a biaxial and coaxial configuration have been studied by transmission electron microscopy. The Young's modulus of the biaxially structured nanowires was measured to be 50-70 GPa depending on the size of the nanowire. © 2000 American Institute of Physics.
