On-lattice Monte Carlo simulations of colloidal random-stacking hard-sphere colloidal crystals are presented. The model yields close-packed crystals with random-stacking hexagonal structure. We find a significant amount of in-plane stacking disorder, which slowly anneals in the course of the simulation. The in-plane stacking disorder leads to lateral broadening of the stacking-disorder-induced Bragg rods. It is found that not only the scattering intensity, but also the width is modulated along the Bragg rods.
本文介绍了胶体随机堆积硬球胶体晶体的晶格蒙特卡罗模拟。该模型产生具有随机堆积六方结构的密堆积晶体。我们发现存在大量的面内堆积无序，在模拟过程中这种无序会缓慢退火。面内堆积无序导致堆积无序诱导的布拉格棒发生横向展宽。结果发现，不仅散射强度，而且宽度也沿布拉格棒发生调制。
