Shell effects in alkali metal nanowires
After making a cold weld by pressing two clean metal surfaces together, and gradually separating the two pieces, a metallic nanowire is formed, which is progressively thinning down to a single atom before the contact is lost. We show evidence that the radii of such nanowires are influenc...

| description |
After making a cold weld by pressing two clean metal
surfaces together, and gradually separating the two pieces, a metallic nanowire is formed,
which is progressively thinning down to a single atom before the contact is lost. We show
evidence that the radii of such nanowires are influenced by electronic shell filling
effects, in analogy to electronic shell structure in metal clusters. A modulation of the
shell effect, known as supershell structure, is clearly observed. For sodium and potassium
at larger diameters there is a crossover to crystalline facets with shell-closings
corresponding to the completion of an additional atomic layer. We conclude that a complete
analogy exists between shell structure in metallic clusters and nanowires. |
