摘要: We present a numerical study of colloidal crystal growth on finite templates. Specifically, we consider planar, crystalline templates with the structure 100, 110, and 100 faces fcc crystal. explore how size induced crystallites depends template area, lattice spacing degree supersaturation. find that thermal fluctuations templating particles around their average positions have strong effect grow epitaxially. If exceed Lindemann criterion, cease to function as crystallization seed. our results are well described by suitably modified version classical nucleation theory.
