Anatomy of point-contact Andreev reflection spectroscopy from the experimental point of view
Anatomy of point-contact Andreev reflection spectroscopy from the experimental point of view
We review applications of point-contact Andreev-reflection spectroscopy to study elemental superconductors, where theoretical conditions for the smallness of the point-contact size with respect to the characteristic lengths in the superconductor can be satisfied. We discuss existing theoretical models and identify new issues that have to be solved, especially when applying …
