Electronic structure of cylindrical simple-metal nanowires in the stabilized jellium model

The ground-state electronic structures of cylindrical quantum wires are stu died within the stabilized jellium model and using the spin-dependent densi ty-functional theory. The subband structure is shown to affect the cohesive properties, causing an oscillating structure in the force needed to elonga te the wire. Because the steps in the quantized conductance reflect also th e subband structure a correlation between the force oscillations and conduc tance steps is established. The model also predicts magnetic solutions comm ensurate with the subband structure and consequently additional steps in th e conductance. [S0163-1829(99)02719-8].
