Point-contact Andreev-reflection spectroscopy in anisotropic superconductors: the importance of directionality (Review Article)

Point-contact Andreev-reflection spectroscopy (PCARS) has demonstrated to be one of the most effective experimental tools for the investigation of fundamental properties of superconductors such as the superconducting gap and the electron–phonon (or, more generally, electron–boson) coupling.
