Mechanisms of normal reflection at metal interfaces studied by Andreev-reflection spectroscopy
Andreev-reflection spectroscopy of elemental superconductors in contact with nonmagnetic normal metals reveals that the strength of normal-reflection varies only slightly. This observation imposes strong constrictions on the three possible normal-reflection mechanisms: tunneling through a dielectr...

| description |
Andreev-reflection spectroscopy of elemental superconductors in contact with nonmagnetic normal metals
reveals that the strength of normal-reflection varies only slightly. This observation imposes strong constrictions
on the three possible normal-reflection mechanisms: tunneling through a dielectric barrier, reflection due to the
different electronic properties of the two electrodes, and diffusive transport caused by elastic scattering in the
contact region. We discuss in detail the role played by Fermi-surface mismatch, represented by the different
Fermi velocities on both sides of the contact interface. We find that it is at least not the dominant mechanism and
possibly completely absent in the Andreev-reflection process.
