| Outline of Final Research Achievements |
Palladium atoms were intercalated between the zero layer graphene grown on the SiC(0001) surface and the substrate. Then its structure and electron states were studied. After the deposition of Pd atoms on the zero layer, Pd atoms were intercalated during the annealing above 700 degrees Celsius. A Dirac cone appeared at the K bar point after the intercalation of Pd atoms. In other words, the zero layer became electrically an ideal graphene because of the intercalation of Pd atoms. The Dirac point is located at the Fermi energy, which indicates that the graphene on the intercalated Pd atoms is electrically neutral. However, it was turned out that a charge transfer occurred between the Pd atoms and the SiC substrate.
