Outline of Final Research Achievements

The mechanism of field emission (FE) from carbon-related materials have not been clarified so far. Although the purpose at the beginning of this study is to clarify the mechanism of superior FE features from fully carbonized mechanical pencil lead, we could not find the way to obtain a required nano-sharp lead tip, which is dispensable for this study. Instead we have investigated FE from a C60 molecule adsorbed on a W tip as a well-defined carbon material. And we have found that the adsorbed C60 molecule shows various FE patterns corresponding to super-atomic molecular orbitals, specific for this molecule, indicating a clear feature to reveal the mechanism of FE from carbon-related materials.
