Abstract
A set of ideas about the homogeneous variable zone structure in the near-surface region of ionic crystals is presented. Its origin is shown using generalizations of the Seitz–Madelung scheme. A number of important consequences have been demonstrated: the peculiarity of local surface levels different from Tamm levels; increase in the critical temperature of superconductivity in a sandwich structure; a significant anti-degradation role of these levels in the processes of energy exchange at the interfaces. It is concluded that such homo varizonality is an excellent example of the implementation of the “Bonds and Bands” concept.
