论文摘要
{\ IT表面指导的旋缺骨分解}（SDSD）是相位分离和表面润湿的动力学相互作用。这个过程具有巨大的科学和技术重要性。在本文中，我们报告了SDSD对化学图案化底物的数值研究的结果。我们考虑模拟的简单表面模式，但是大多数结果适用于任意模式。在表面附近的层中，我们观察到从{\ IT表面注册机制}到{\ it相分离制度}的动态交叉。我们使用层的相关函数和结构因子以及域长度尺度研究了这种交叉。
{\it Surface-directed spinodal decomposition} (SDSD) is the kinetic interplay of phase separation and wetting at a surface. This process is of great scientific and technological importance. In this paper, we report results from a numerical study of SDSD on a chemically patterned substrate. We consider simple surface patterns for our simulations, but most of the results apply for arbitrary patterns. In layers near the surface, we observe a dynamical crossover from a {\it surface-registry regime} to a {\it phase-separation regime}. We study this crossover using layer-wise correlation functions and structure factors, and domain length scales.
