  Although C$_{60}$ is a molecular crystal with a bandgap E$_g$ of ~2.5 eV, we
show that E$_g$ is strongly affected by injected charge. In sharp contrast to
the Coulomb blockade typical of quantum dots, E$_g$ is {\it reduced} by the
Coulomb effects. The conductance of a thin C$_{60}$ layer sandwiched between
metal (Al, Ag, Au, Mg and Pt) contacts is investigated. Excellent Ohmic
conductance is observed for Al electrodes protected with ultra-thin LiF layers.
First-principles calculations, Hubbard models etc., show that the energy gap of
C$_{60}$ is dramatically reduced when electrons hop from C$_{60}^-$ to
C$_{60}$.
