Abstract Nucleation is an important step in crystallization, and many self-organized patterns are determined in this process. In this study, after briefly reviewing the fundamentals of nucleation theory, we take a few examples to show the significance of concave-corner-mediated nucleation in both self-organized formation of long-range-ordered patterns and in self-assembly of metallic nano wire array. We show that successive concave-corner-mediated nucleation on the growth front is an important mechanism leading to many long-range ordering effects in crystallization. This mechanism can also be applied in fabricating metallic nano wires with specific geometry, including straight metallic wire array with tunable line width and nanowires with periodic structures.

选择性成核和自组织结晶

摘要 成核是结晶过程中的一个重要步骤，在此过程中确定了许多自组织模式。在这项研究中，在简要回顾了成核理论的基础之后，我们举了几个例子来说明凹角介导的成核在长程有序图案的自组织形成和金属纳米自组装中的重要性。线阵列。我们表明，生长前沿上连续的凹角介导的成核是导致结晶中许多长程有序效应的重要机制。这种机制也可以应用于制造具有特定几何形状的金属纳米线，包括具有可调线宽的直线金属线阵列和具有周期性结构的纳米线。
