Title: | Core-shell SiC/SiO2 heterostructures in nanowires | Authors: | Wu, Renbing Zha, Bailin Wang, Liuying Zhou, Kun Pan, Yi |
Keywords: | DRNTU::Engineering::Mechanical engineering | Issue Date: | 2012 | Source: | Wu, R., Zha, B., Wang, L., Zhou, K., & Pan, Y. (2012). Core-shell SiC/SiO2 heterostructures in nanowires. Physica status solidi (a), 209(3), 553-558. | Series/Report no.: | Physica status solidi (a) | Abstract: | This paper presents a simple vapour deposition method for one-step synthesis of SiC//SiO2 core-shell heterostructured nanowires. The phases, structures and morphologies of the synthesized core-shell heterostructures are systemically studied by field emission scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and high-resolution transmission electron microscopy. The results show that these heterostructures consist of a single crystalline SiC core of 20∼30 nm diameter covered by a uniform layer, about 15 nm thickness of amorphous SiO2. Such heterostructures were grown based on the vapour–solid mechanism and the deposition way has an important influence on their morphology. A unique optical property has also been found in their photoluminescence spectra that have blue shift relative to the bulk SiC. | URI: | https://hdl.handle.net/10356/105226 http://hdl.handle.net/10220/17084 |
