Layer plasmons and high-Tc superconductivity
Abstract
We study a layered electron-gas model for the high-Tc copper oxides. The formation of plasmon bands by the interlayer Coulomb interaction is shown to lead to enhanced plasmon-induced electron pairing at the boundaries of the plasmon bands. We comment on the potential contribution of quasi-one-dimensional plasmons for the YBa2Cu3O7- compounds. The concept of coexistence of phonon and plasmon mechanisms is discussed. © 1988 The American Physical Society.
