Título: | Molecular beam growth of graphene nanocrystals on dielectric substrates |
Autor: | Wurstbauer, Ulrich; García Martínez, Jorge Manuel CSIC ORCID CVN | Fecha de publicación: | 14-feb-2012 | Editor: | Elsevier | Citación: | Carbon 50 (13): 4822-4829 (2012) | Resumen: | We demonstrate the growth of graphene nanocrystals by molecular beam methods that employ a solid carbon source, and that can be used on a diverse class of large area dielectric substrates. Characterization by Raman and Near Edge X-ray Absorption Fine Structure spectroscopies reveal a sp2 hybridized hexagonal carbon lattice in the nanocrystals. Lower growth rates favor the formation of higher quality, larger size multi-layer graphene crystallites on all investigated substrates. The surface morphology is determined by the roughness of the underlying substrate and graphitic monolayer steps are observed by ambient scanning tunneling microscopy. | Descripción: | Ulrich Wurstbauer et al. | Versión del editor: | http://dx.doi.org/10.1016/j.carbon.2012.06.008 | URI: | http://hdl.handle.net/10261/46683 | DOI: | 10.1016/j.carbon.2012.06.008 | ISSN: | 0008-6223 |
