Proximity effect from an andreev perspective

Webb6 aug. 2024 · In regions of strong inhomogeneity, multiple Andreev reflection leads to the formation of sub-gap states, Andreev bound states, with excitation energies below the superconducting gap. These states play a central role in our understanding of inhomogeneous superconductors. The discoveries of unconventional superconductivity … Webb13 maj 2012 · The proximity effect, usually described as the penetration or ‘leakage’ of the superconducting condensate from a S into an overlaying normal metal (N), is on a microscopic level the result of ...
