Abstract
We study the effects of the Coulomb electron-electron interaction on the Aslamazov-Larkin fluctuation correction to the conductivity in impure two-dimensional metals. We show that unlike the correction to the superconducting transition temperature, the above correction to the conductivity is sensitive to the form of the Coulomb interaction. In particular we studied the case of a thin metallic film separated from a massive metallic substrate by an insulator, when the electron-electron interaction is modified by image forces.
