Abstract
âºWe calculate the electric conductances of atomic contacts consisting of Au, Al and Pt based on nonequilibrium Green's function theory and phase shift analysis. âºWe analytically introduce the charge neutrality condition through the Friedel sum rule. âºWe have analytically shown that the electric conductances are quantized and can increase when the distance between two electrodes increases. âºWe conclude that the increment of the electric conductance is interpreted by the Friedel sum rule.
