| Outline of Final Research Achievements |
We have developed novel CVD process system, which enables us to produce graphene nano-structures on the specific part on the substrate, and investigated their physical properties by scanning probe microscopy without exposing them to atmospheric condition. At the very early stage of CVD process on Cu substrate, two kinds of nano-meter clusters, triangular type and hexagonal one, were found, and, by proceeding the growth, only hexagonal-type could be found, and that some of which formed nano-ribbon structures with their width of around 10nm under specific process condition. The LCPD (Local Contact Potential Difference) values of the surfaces were observed, and found that they gradually converge to the LCPD value of HOPG with increasing the number of sheet stacking.
