Kinetically induced ordering oscillation during epitaxial growth of a fcc multilayer alloy
Abstract
The kinetics of ordering in fcc multilayer alloys during the epitaxial growth is investigated by the kinetic mean-field method. The kinetic phase diagrams for the epitaxial alloy of a fcc multilayer are calculated. We have found that there is a kinetically induced oscillatory ordered phase in addition to the equilibrium ordered phase in the kinetic phase diagrams. This ordering oscillation is caused by the kinetic correlation of different growth processes. It occurs with growth condition of higher deposition rate and in materials with high jumping barrier energies.
