The electronic properties of fullerene-based nanostructures A(C₆₀)₂ (A – alkali atom) are examined by first-principles calculations based on the density functional theory. The electron conductivity of the (C₆₀)₂ dimer is low owing to the constraint of the junction of the molecules. When the fullerene dimer are doped by inserting an alkali atoms A, the unoccupied state around the junction is filled and the conductivity can be significantly improved.
