Jellium model of metallic nanocohesion
arXiv:cond-mat/9709031 · doi:10.1103/PhysRevLett.79.2863
Abstract
A unified treatment of the cohesive and conducting properties of metallic nanostructures in terms of the electronic scattering matrix is developed. A simple picture of metallic nanocohesion in which conductance channels act as delocalized chemical bonds is derived in the jellium approximation. Universal force oscillations of order epsilon_F/lambda_F are predicted when a metallic quantum wire is stretched to the breaking point, which are synchronized with quantized jumps in the conductance.
