Point-contact spectroscopy of the electron-phonon interaction in palladium

Results are reported of the experimental point-contact spectroscopy and of the theoretical investigation of the electron--phonon interaction (EPI) in Pd. It is shown that positions of the peaks in the point-contact spectral function are determined by the structure of the phonon spectrum, while their...

Beschreibung
Zusammenfassung:Results are reported of the experimental point-contact spectroscopy and of the theoretical investigation of the electron--phonon interaction (EPI) in Pd. It is shown that positions of the peaks in the point-contact spectral function are determined by the structure of the phonon spectrum, while their relative intensities depend on the Fermi surface topology and EPI anisotropy.
