We have analyzed the atomic arrangements and quantum conductance of silver nanowires generated by mechanical elongation. The surface properties of Ag induce unexpected structural properties, as for example, predominance of high aspect ratio rod-like wires. The structural behavior was used to understand the Ag quantum conductance data and the proposed correlation was confirmed by means of theoretical calculations. These results emphasize that the conductance of metal point contacts is determined by the preferred atomic structures and, that atomistic descriptions are essential to interpret the quantum transport behavior of metal nanostructures.

• Quantum properties of atomic-sized conductors (2002, methodology): “[220] have used a MCBJ under UHV at room temperature and found a conductance histogram for Ag that, apart from the peak just below 1G0, has a rather strong peak at 2:4G0 and a broader feature just above 4G0.”
