“…We have also shown from RPES studies on the alloys with x >> x C2 that the newly appeared band has Re5d like character [22]. Further analysis by Evans and Dowben revealed stronger Mo-Re orbital hybridization for x >> x C2 in comparison with the Mo-Mo or Re-Re bonding [36].…”

We present the results of resonant photoemission spectroscopy experiments on the Mo 1−x Re x alloy compositions spanning over two electronic topological transitions (ETT) at the critical concentrations x C1 = 0.05 and x C2 = 0.11. The photoelectrons show an additional resonance (R3) in the constant initial state (CIS) spectra of the alloys along with two resonances (R1 and R2) which are similar to those observed in molybdenum. All the resonances show Fano-like line shapes.The asymmetry parameter q of the resonances R1 and R3 of the alloys is observed to be large and negative. Our analysis suggests that the origin of large negative q is associated with phonon assisted inter band scattering between the Mo-like states and the narrow band that appeared due to the ETT.

“…In the alloys, the resonance R2 becomes sharper (Γ(x =0)< 0.5Γ(0)) with a q ≈ 1.2 due to the preferential Mo-Re bonding over the Mo-Mo or Re-Re bonding [36]. The shape of the resonance R1 in the alloys is quite different from that of molybdenum.…”

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 MoReO x 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.
