Solid state chemistry for connecting the pieces of the high-Tc superconducting puzzle?

摘要

In high-Tc cuprates, superposition to a localized low-energy antiferromagnetic background of a delo-calized high-energy assembly of exciton-solvated doping holes (ESH) accounts for singlet state hole pairing in real space, above T_C. Below T_C pairs can glide in coherent motion along one-dimensional spines, formed by aligned charge transfer excitons, and serving as rails. Most of old and new experi-mental observations agree with this model. In high-Tc cuprates, Coulomb interactions between exciton-solvated doping holes (ESH) can result in real-space pairing of holes.
