| Research Abstract |
We try NMR on a monolayer of graphite film. As an early stage, we detected a change in conductance caused by oxygen adsorption onto the film surface. We investigated the temperature dependence of the change in conductance. But the detection sensitivity of our system turned out to be low since the film surface was not clean enough. We modified the micro fabrication process and tried several annealing methods (annealing in the mixture of hydrogen and argon, current annealing etc.) for preparing clean surface but remarkable improvement was not obtained. We continue this research and make measurements with a scanning probe microscope and a scanning near field optical microscope for the information on surface contamination.
