摘要：

We address the question whether or not acoustic collective modes contribute to superconductivity in a layered electron, gas. We calculate T-c within the strong-coupling phonon-plasmon scheme. The plasmon pairing kernel is calculated explicitly. We demonstrate that plasmons may contribute constructively to superconductivity. The result shows that one can interpret the effect of low-energy collective modes in terms of an effective negative mu*.
