Varizonicity and surface levels in ionic crystals

It is shown that in this case the electronic structure of the surface states becomes special – a near-surface potential well appears, as a result of which the local states radically differ from the Tammov states.

Description
Summary:The problem of the formation of varizonicity in ionic crystals is investigated. It is shown that in this case the electronic structure of the surface states becomes special – a near-surface potential well appears, as a result of which the local states radically differ from the Tammov states. A similar effect, in principle, should take place in cases of varizonicity of covalent crystals, which is due to special alloying in them. A consideration is made about the special situation in HTS materials: a combination of external and internal varizonality.
