Andreev-reflection spectroscopy with superconducting indium - a case study
Kurt Gloos, Elina Tuuli
We have investigated Andreev reflection at interfaces between superconducting indium (T_c = 3.4 K) and several normal conducting non-magnetic metals (palladium, platinum, and silve…
Electron and hole transmission through superconductor - normal metal interfaces
Kurt Gloos, Elina Tuuli
We have investigated the transmission of electrons and holes through interfaces between superconducting aluminum (Tc = 1.2 K) and various normal non-magnetic metals (copper, gold,…
Spin polarization versus lifetime effects at point contacts between superconducting niobium and normal metals
Elina Tuuli, Kurt Gloos
Point-contact Andreev reflection spectroscopy is used to measure the spin polarization of metals but analysis of the spectra has encountered a number of serious challenges, one of…
Normal reflection at superconductor - normal metal interfaces due to Fermi surface mismatch
Elina Tuuli, Kurt Gloos
Electrons can be reflected at an interface between two metals because of a dielectric barrier or different properties of the Fermi surface. Andreev reflection allows to directly me…
Break-junction experiments on the zero-bias anomaly of non-magnetic and ferromagnetically ordered metals
Kurt Gloos, Elina Tuuli
We have investigated break junctions of normal non-magnetic metals as well as ferromagnets at low temperatures. The point contacts with radii 0.15 - 15 nm showed zero-bias anomalie…
Phonon-drag induced suppression of the Andreev hole current in superconducting niobium contacts
Kurt Gloos, Jouko Huupponen, Elina Tuuli
We have investigated how the Andreev-reflection hole current at ballistic point contacts responds to a large bias voltage. Its strong suppression could be explained by the drag exc…
