The effects of the Hubbard exchange-correlation term G(k) on the normal 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 {approx} 1/c, where c is the interlayer separation, is satisfied. For lower carrier densities, the plasmon-mediated superconductivity is suppressed, whereas at higher densities superconductivity can exist with T{sub c} having a bell-shape dependence on the carrier density.
