Ss. Shilstein et al., COULOMB SPLITTING OF ATOMIC LAYERS IN CRYSTAL LATTICES OF LAYERED CUPRATES AND NICKELATES, Physica. C, Superconductivity, 245(1-2), 1995, pp. 181-185
The crystal structure data are collected and analyzed on the splitting
of anion-cation layers with non-symmetric electric charge environment
. It is shown that the effect is caused by Coulomb interaction with th
e other charged layers, mainly the nearest neighboring ones. The feasi
bility is demonstrated of the control of interlayer charge transfer by
magnitude of the Coulomb splitting. The correlation between the Coulo
mb splitting of (BaO) layers, neighboring to (CuO2), and superconducti
ng transition temperature T-c is found in yttrium-barium cuprates.
