Zusammenfassung: | The mechanism of electron-phonon interaction in the Mo0.73Re0.27 alloy in the Ag-I-Mo0.73Re0.27 tunnel contact, where the dielectric I is formed on natural MoReOx oxide, was investigated for the first time. This approach helped to avoid the proximity effect, which is inherent in a wide range of contacts with the oxidized Al layer. Due to the lack of a negative proximity effect, which leads to a zero anomaly in the tunneling conductivity, the scale of which exceeds the fine structure of the electron-phonon interaction, it was possible to obtain the characteristics of the phonon spectrum of the studied molybdenum-rhenium alloy. The obtained results are in good agreement with the data from thermal conductivity measurements, point-contact and neutron spectroscopy. |
