LATTICE DYNAMICAL ASPECTS OF PHASE TRANSITIONS IN ADSORBED MONOLAYERS
Résumé
We present some aspects of second ordrer phase transitions in connection with the possible existence of soft surface modes. The theory takes due account of the variation with temperature of the force constants bounding all the atoms, especially the adatoms to the substrate. This variation may enable a phonon to become soft at a given temperature.
