Low temperature route synthesis of SiC-Al_2O_3 hetero-structural nanofibers

摘要

SiC-Al_2O_3 hetero-structural nanofibers have been synthesized by the chemical solution approach at 200°C. The diameters of nanofibers are in the range of 60-100 nm while the lengths are from tens of micrometers to hundreds of micrometers. The microstructural analysis shows that the fibers possess a like-epitaxial relationship between (104) of hexagonal Al_2O_3 and (111) of cubic SiC. Additionally, the optical investigation of the nanofibers suggests there are some defects in the low annealing temperature synthesized SiC-Al_2O_3 nanofibers.
