摘要
We present first-principles calculations of electron conduction properties of monatomic sodium wires suspended between semi-infinite crystalline electrodes, using the overbridging boundary-matching method. We find that the conductances oscillate depending on the number of atoms in the wire, N-atom, Furthermore, the values of conductances are similar to3 G(0) (G(0) = 2e(2)/h) for the closed packed structure and similar to1 G(0) for single-row wires, which is in agreement with the experimental results of the conductance histogram.
