摘要
We consider a simple model of a metallic nanowire, consisting of a free electron gas confined within hard-wall boundaries and connected to banks on either side. Similar models have been widely used to discuss conductance properties of nanowires and point contacts. Here we show that the same model has implications for the mechanical stability of the wire and its work function, and that it possibly induces Jahn-Teller-type distortions in the wire cross section.
