摘要：
We discuss a scenario for interface-induced superconductivity involving pairing by dipolar excitations proximate to a two-dimensional electron system controlled by a transverse electric field. If the interface consists of transition-metal oxide materials, the repulsive on-site Coulomb interaction is typically strong and a superconducting state is formed via exchange of nonlocal dipolar excitations in the d-wave channel. Perspectives to enhance the superconducting transition temperature are discussed.
