Charge complementarity and interlayer coupling between charge ordered layers of cuprates

Research output: Contribution to journalArticle

Abstract

The interlayer Coulomb coupling between charge ordered superlattices with charge antisymmetry has been studied. The 2D pair-condensate can be characterized by a charge ordered state with a "checkerboard" like pattern seen recently by scanning tunneling microscopy. Interlayer charge complementarity is essential for getting interlayer energy gain which is found to be proportional to the condensation energy. The correlation between the condensation energy and the critical temperature is studied within our charge ordered superlattice bilayer model in which pairing is supported by interlayer Coulomb energy gain (potential energy-driven superconductivity). The static c-axis dielectric constant εc is calculated for various cuprates and compared with the available experimental data.
