Abstract
Interaction between the electrons and phonons determines some of the most fundamental properties of solids, including superconductivity, thermal and thermoelectric transport, polaronic effects, and electrical resistance in metal at high temperatures. In good metals, particularly noble metals such as gold (Au), silver (Ag), or copper (Cu), the coupling of electrons and phonons is rather weak [1], and the electron-phonon coupling constant () is small. The corresponding electron-
phonon scattering rate provides an excellent quantitative description of the metallic resistivity when the temperature () exceeds the Debye temperature (). The regime of however, remained experimentally inaccessible so far, raising questions on possible universal Planckian bound on scattering rate [2], polaronic deformation, or indeed, even the stability of a metallic state itself [3]. In this work [6], we demonstrate how coulomb interactions at the nanoscale interface of Au and Ag (of
radius nm) [4] that allow...
