Phase transitions in adsorbed layers formed on crystals of square and rectangular surface lattice

摘要: Abstract This article gives a survey of phase transitions in adsorbed films on well defined surfaces square and rectangular symmetry the lattice. The discussion concentrates effects periodic changes adsorbate–substrate potential structure thermodynamic properties films. Different theoretical approaches are briefly reviewed, with an emphasis those which explicitly take into account final corrugation surface potential. Several aspects statistical mechanical description layers, such as order–disorder, melting, commensurate–incommensurate monolayer connected formation multilayer (layering wetting) presented. Theoretical is followed by presentation numerous experimental computer simulation studies for various systems. Then molecular adsorbates different substrates discussed. It pointed out that methods provide very powerful tool allows to probe inner systems provides direct information concerning both orientational positional ordering.
