ScholarBank@NUS Repository. https://doi.org/10.1063/1.2200353 | Abstract: | Two-dimensional carbon nanowalls (CNWs) were prepared by microwave plasma-enhanced chemical-vapor deposition and scanning electron microscopy was used to observe their morphologies. The Raman observations of different sample orientations and polarizations show that CNWs are well crystallized. Micro-Raman scattering measurements were also carried out with different excitation laser lines (325, 488, 514, 532, and 633 nm). The D band shows a very strong shift of 46.19 cm-1 eV with excitation laser energy and this has been explained by the double resonance effect. The decreasing intensity ratios ID IG and I D′ IG with increasing laser excitation energy were detected and discussed. © 2006 American Institute of Physics. | Source Title: | Journal of Chemical Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/97739 | ISSN: | 00219606 | DOI: | 10.1063/1.2200353 |
