Abstract

The influence of patterned surfaces on the formation of one- and two-dimensional colloidal crystals is analyzed. We have used the corrugated surface of a digital versatile disc (DVD) for template surface processing. When the sphere diameter is on the order of the groove width of patterned substrates, a rich variety of particle decorations appear. However, if particle size is much larger than template patterns, large domains of particle ordering are formed.

摘要

分析了图案表面对一维和二维胶体晶体形成的影响。我们使用数字通用光盘（DVD）的波纹表面作为模板表面处理。当球体直径与图案基底的凹槽宽度相当时，会出现各种丰富的颗粒装饰。但是，如果颗粒尺寸比模板图案大得多，则会形成颗粒有序的大畴。
