Transport and Noise Characteristics of Submicron High-Temperature Superconductor Grain-Boundary Junctions
F. Herbstritt, T. Kemen, L. Alff +2
We have investigated the transport and noise properties of submicron YBCO bicrystal grain-boundary junctions prepared using electron beam lithography. The junctions show an increas…

Andreev Bound States in High Temperature Superconductors
L. Alff, S. Kleefisch, U. Schoop +5
Andreev bound states (ABS) at the surface of superconductors are expected for any pair potential showing a sign change in different k-directions with their spectral weight dependin…
