Query: The dominance of non-electron-phonon charge carrier interaction in
  highly-compressed superhydrides   The primary mechanism governing the emergence of near-room-temperature
superconductivity in superhydrides is widely accepted to be the electron-phonon
interaction. If so, the temperature dependent resistance, R(T), in these
materials should obey the Bloch-Gr\"uneisen equation, where the power-law
exponent, p, should be equal to the exact integer value of p=5. On the other
hand, there is a well-established theoretical result that pure electron-magnon
interaction should be manifested by p=3, and p=2 is the value for pure
electron-electron interaction. Here we aimed to reveal the type of charge
carrier interaction in the layered transition metal dichalcogenides PdTe2,
high-entropy alloy (ScZrNb)0.65[RhPd]0.35, and highly-compressed elemental
boron and superhydrides H3S, LaHx, PrH9 and BaH12 by fitting the temperature
dependent resistance of these materials to the Bloch-Gr\"uneisen equation where
the power-law exponent, p, is a free-fitting parameter. In the result, we
showed that the high-entropy alloy (ScZrNb)0.65[RhPd]0.35 exhibited pure
electron-phonon mediated superconductivity with p = 4.9. Unexpectedly we
revealed that all studied superhydrides exhibit 1.8 < p < 3.2. This implies
that it is unlikely that the electron-phonon interaction is the primary
mechanism for the Cooper pairs formation in highly-compressed superhydrides and
alternative pairing mechanisms, for instance, the electron-magnon, the
electron-polaron, the electron-electron or other, should be considered as the
origin for the emergence of near-room-temperature superconductivity in these
compounds.
