Dimensionality effects on non-equilibrium electronic transport in Cu nanobridges
arXiv:cond-mat/0311287 · doi:10.1103/PhysRevB.70.033407
Abstract
We report on non-equilibrium electronic transport through normal-metal (Cu) nanobridges coupled to large reservoirs at low temperatures. We observe a logarithmic temperature dependence of the zero-bias conductance, as well as a universal scaling behavior of the differential conductance. Our results are explained by electron-electron interactions in diffusive metals in the zero-dimensional limit.
