Abstract

Damping of the quasiparticles in a layered two-dimensional electron gas has been calculated including the electron-phonon and electron-electron interaction. The calculations performed atT=0 andT≠0 show that the non-Fermi behavior can appear as in the case of the electron-plasmon interaction, but it is also enhanced by the presence of the phonons.
