5. Two-dimensional phase transitions

For the sake of brevity, paragraphs 5 and will deal only with phase transitions in physisorbed films. For the whole of this section, please refer to the bibliographical references ( ).

5.1 Definitions

In adsorption, a two-dimensional phase transition, or 2D transition, is usually understood as the passage of a monomolecular layer of the film from one state to another (e.g. from a diluted to a condensed state). The limiting case is one in which...
