Abstract
The effects of the Hubbard exchange-correlation term G(k) on the norma l and superconducting state properties of a layered 2D system has been investigated. It is shown that it can induce a metal-insulator phase transition when the condition (PF) approximate to 1/c, where c is the interlayer separation, is satisfied. For lower carrier densities, the plasmon-mediated superconductivity is suppressed, whereas at higher de nsities superconductivity can exist with T-c having a bell-shape depen dence on the carrier density.
