TUNNELING-INDUCED SUPERCONDUCTIVITY IN LAYERED SYSTEMS

[摘要] We studied electron-phonon interactions in systems consisting of conducting layers separated by insulating media. The conducting layers are treated as two-dimensional Fermi liquids, and the interaction between them is assumed to be tunneling. Phonon modes modifying the interlayer distances are found to lead to an attractive electron-electron interaction which can induce a superconducting transition.
