利用外延生长的实际模型，研究了亚单分子层外延生长中岛尺寸分布的动态标度及其与临界岛尺寸i的关系，并给出了标度岛尺寸分布随i变化的解析表达式。我们的结果与Fe/Fe(100)和Fe/Cu(100)沉积的实验结果很好地吻合。给出了孤岛密度和临界孤岛尺寸随温度和沉积速率变化的交叉标度形式。
The dynamic scaling of the island-size distribution in submonolayer epitaxial growth and its dependence on the critical island size i is studied using a realistic model of epitaxial growth for i= 0, 1, 2, and 3. An analytic expression for the scaled island-size distribution as a function of i is also proposed. Our results agree well with experiments on Fe/Fe (100) deposition and on Fe/Cu (100) deposition. Crossover scaling forms for the variation of the island density and critical island size as a function of temperature and deposition rate are also presented.
