Abstract: The effects of different contact geometries, bond dimerization, and gatevoltage on quantum transport through a C$ {60}$ molecule are studied by theLandauer-B\-{u}ttiker formula based on the Green-s function technique. It isshown that the number of contact points between the device electrodes and themolecule can play an important role in the electron conduction. Thetransmission is due to the resonant tunneling when the electrodes are contactedto one carbon atom of the molecule. In the case of multiple contacts, theinterference effects are responsible for the change of the transmission throughthe C$ {60}$. The bond dimerization and a gate voltage shift the molecularlevels and by adjusting the related parameters the electron conduction can becontrolled.
