The beginning of this century saw the pioneering fabrication of a single molecular transistor using a single C60 molecule between gold nanowires, and inspired experimentalists and theorists alike to focus on studying phonon assisted transport through nanoscale electronic devices. We have formulated an electron tunnelling model for the current-voltage (I-V) relationship for a C60 molecular transistor that reproduces trends observed in the experimental I-V curves. A uniform one dimensional tight-binding lattice is used to model the transistor system, with a central defect site representing the molecule. The current is written as a function of tunnelling rates on and off of …
