Resistivity and Electron-Phonon Coupling in Palladium Alloy Hydrides
Palladium copper hydrides have been fabricated by coevaporating palladium with copper and subsequently implanting hydrogen ions. The change in high temperature resistivity as a function of temperature upon implantation is measured and correlated to the electron-phonon coupling parameter λ. This Correlation is in good agreement with the observation of high superconducting temperatures in Pd1−xCuxHy.
