ファセット端近傍の結晶形の緩和(<特集>ステップの統計力学と結晶成長)

抄録

The relaxation process of the crystal shape near the facet is studied by means of a time-dependent Ginzburg-Landau equation. During the relaxation process, the surface gradient p behaves as p〜(⊿x)^<l/2> (⊿x: distance from the facet edge) off the facet edge and p〜⊿x quite near the facet edge. This result gives a possible explanation for the discrepancy between theory and experiment on the facet edge critical behavior.
