Abstract
Point-contact spectroscopy was originally developed for the determination of theelectron–phonon spectral function in normal metals. However, in the past 20 years it hasbecome an important tool in the investigation of superconductors. As a matter of fact,point contacts between a normal metal and a superconductor can provide information onthe amplitude and symmetry of the energy gap that, in the superconducting state, opensup at the Fermi level. In this paper we review the experimental and theoretical aspects ofpoint-contact spectroscopy in superconductors, and we give an experimental survey of themost recent applications of this technique to anisotropic and multiband superconductors.
