薄膜尺寸效应对表面临界行为的影响

INFLUENCE OF SIZE EFFECT ON CRITICAL BEHAVIORS AT FILM SURFACE

本文利用平均场理论讨论了薄膜尺寸效应对表面物理量临界指数及表面标度律的影响,说明表面临界行为亦存在渡越现象.

By using mean field theory, we discuss the influence of size effect on surface exponenu and scaling laws of a film. We indicate that a crossover phenomenon would appear.
