Nanoscale integration of SiC/SiO_2 core-shell nanocables in diamond through a simultaneous hybrid structure fabrication

摘要

The nanoscale integration of SiC nanocables in a diamond thin film is achieved through a novel synthetic pathway, which combines Fe catalyst and detonation nanodiamond seeding technique in a microwave plasma chemical vapor deposition process. The obtained hybrid structures show controllable SiC nanocable fraction depending on the relative fraction of iron catalyst and diamond seeds. The SiC nanocable has a conical structure with l0nm diameter SrC core, surrounded by SiO_2 shell. The diamond crystals show high quality/cry stallinity even for hybrid structures featuring an increasing SiC nanocable fraction. In the end, the growth behavior of the hybridstructure is discussed.
