Extra oxygen and carrier distribution in CuO₂ layers in HgBa₂Can₋₁CunO₂n₊₂₊δ compounds (n=1,2,4)
It is proposed to determine the equilibrium state of the crystal lattice by minimizing the total energy in order to elucidate the role of electrostatic interactions as well as to determine the nonstoichiometry in Hg-contained high temperature superconductors (HTSC). The approximation of non-inter...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | It is proposed to determine the equilibrium state of the crystal lattice by
minimizing the total energy in order to elucidate the role of electrostatic
interactions as well as to determine the nonstoichiometry in Hg-contained
high temperature superconductors (HTSC). The approximation of non-interacting holes is used to evaluate the band energy. Such an approach
enables us to satisfactorily describe the changes of oxygen nonstoichiometry and to indicate the preferred localization of the carriers on oxygen sites
in CuO₂ layers. |
