Proximity effects and vortex dynamics in mesoscopic superconductor-normal metal-superconductor arrays
… predicts that, at zero temperature in 1D and 2D systems, the diffusive motion of electrons scattering off impurities ceases, and there is no long range electron transport. In other words, there are no metallic states at T = 0 in 1D and 2D systems. Although this theory has accurately described …
