| Outline of Final Research Achievements |
In order to study the "device with molecular migration" that does not fix a molecule to the electrode, we used the Si(111)-7×7 structure as a template. We studied effect of high-concentration phosphorus doping to the surface structure and co-adsorption of atoms and molecules. It was found that when the sample was treated with the high-concentration phosphorus doping, and was heated in an ultrahigh vacuum, a clean surface structure in which some phosphorus atoms were embedded and a region covered with continuous phosphorus layer were observed. We tried to fabricate a highly-doped sample with a patterned electrode structure, and found that the oxidation rate was extremely high. Molecular migration process by theoretical calculation and metal-molecule co-adsorption experiments on graphene samples are underway.
