| Outline of Final Research Achievements |
A graphene sheet cut into a one-dimensional ribbon form is called graphene nanoribbon (GNR). In GNRs, the band gap is opened depending on the edge arrangement and ribbon width, and therefore, the formation of GNRs in a convenient and controlled manner is important. In this study, GNRs are obtained from n-alkane on a Au(111) surface, which is known to be less reactive catalyst, by thermal dehydrogenation. The molecular orientation of n-alkane is analyzed by in-situ infrared reflection absorption spectroscopy under the electrochemical environment. The orientation depends on the molecular density, and the desorption of molecules precedes the dehydrogenation.
