Possibility of charge-mediated superconductors in the intermediate region of metal-insulator transitions

摘要

Some molecular systems for a charge-mediated superconductor are proposed from the viewpoint of the metallic side and the insulator side. An approach to the charge-transfer (CT) model is presented. Expressions of the effective electron-electron interaction in the charge-fluctuation models is also derived by a field-theoretical approach. (C) 1998 John Wiley & Sons, Inc. [References: 48]
