Abstract
The relaxation process of the crystal shape near the facet is studied. We adopt a dynamical equation which takes account of the nonanalytic behavior of the vicinal-surface free energy to analyze the relaxation process of the crystal shape near the facet. During the relaxation process, the surface gradient p shows the Gruber-Mullins-Pokrovsky-Talapov behavior p∼(Δr)1⁄2 (Δr: distance from the facet edge) off the facet edge. Quite near the facet edge, however, we obtain the ‘classical’ behavior p∼Δr. This result, dynamical transmutation of critical behavior, gives a possible explanation for the discrepancy between theory and experiment on the facet edge critical behavior.
