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.
