We present a thin film device utilizing nano-gap electrodes with nanoscale separations and a fusible fullerene, C₆₀ pyrrolidine tris-acid. This device enables the formation of highly conductive C₆₀ chain through current injection from the electrodes. A change in resistance was observed upon applying voltage to the C₆₀ chain. This resistance variation was consistently reproducible and understood as a resistance switching effect. Furthermore, it was revealed that the formed C₆₀ chain undergo a transition from Poole-Frenkel conduction to Space Charge Limited Current.
