• We succeeded in sandwiching a single carbon fullerene between two (111) facets and measured the conductance at room temperature using a transmission electron microscope combined with a scanning tunneling microscope. The carbon fullerene prevented to move around at the gap when it was slightly compressed between two facets. In this condition, the C80 and C140 fullerenes had the values of 0.53 and $0.62G_{0}$ ($=2e^{2}/h$), respectively, and sometime showed stepwise conductance change due to rotation. Since current–voltage characteristics showed metallic behavior for the C140 fullerene, the single carbon fullerene is thought to have metallic bonds to gold (111) surface under a slight compression, resulting in keeping the same adsorption site.
