Abstract
Electron transport properties of C molecules suspended between gold electrodes are investigated using first-principles calculations. Our study reveals that the conductances are quite sensitive to the number of C molecules between electrodes: the conductances of C monomers are near 1 G, while those of dimers are markedly smaller, since incident electrons easily pass the C molecules and are predominantly scattered at the C-C junctions. Moreover, we find both channel currents locally circulating the outermost carbon atoms.
