Electron-electron scattering in dirty three-dimensional aluminum films
Nonequilibrium superconductivity has been used to determine for the first time the electron-electron scattering rate in weakly disordered three-dimensional aluminum films at temperatures of about 1 K. This electron-electron rate strongly exceeds the independently measured electron-phonon rate for re...

Zusammenfassung: | Nonequilibrium superconductivity has been used to determine for the first time the electron-electron scattering rate in weakly disordered three-dimensional aluminum films at temperatures of about 1 K. This electron-electron rate strongly exceeds the independently measured electron-phonon rate for resistivity rho>100 n..cap omega.. m and is proportional to l/sup -3/2/ as predicted by the Schmid theory. The absolute value exceeds the theoretical value by an order of magnitude. |
