Electron emission from an individual, supportedC60molecule

The electron emission properties of a single ${\mathrm{C}}_{60}$ molecule supported on a W field emission tip are reported. Using standard models, values for the size, effective work function, and desorption temperature of ${\mathrm{C}}_{60}$ were obtained. Energy distributions of electrons emitted from ${\mathrm{C}}_{60}$ exhibit a narrow two-peaked spectrum and indicate a splitting of the highest occupied molecular-orbital level.
