通过蒙特卡罗模拟研究了球形三嵌段片状粒子形成的二维结构。在该模型中，三嵌段斑块粒子在极位具有两种不同类型的斑块。斑块大小不同，吸引相互作用仅在相同类型的斑块之间起作用。粒子在平面上平移并三维旋转。当改变两个补丁的大小，压力和相互作用能，观察到各种结构。当两个补丁之间的差异是小的，可果美晶格，六边形结构，和二维十二方准晶结构观察。当两个面片尺寸之间的差异较大时，会创建链状结构。在较低的温度下，形成诸如环状结构的稀疏结构。
Two-dimensional structures formed by spherical triblock patchy particles are examined by performing Monte Carlo simulations. In the model, the triblock patchy particles have two different types of patches at the polar positions. The patch sizes are different from each other, and the attractive interaction acts only between the same types of patches. The particles translate on a flat plane and rotate three-dimensionally. When varying the two patch sizes, the pressure, and interaction energy, various structures are observed. When the difference between two patch sizes is small, kagome lattices, hexagonal structures, and two-dimensional dodecagonal quasi-crystal structures are observed. When the difference between two patch sizes is large, chain-like structures are created. With lower temperature, sparse structures such as ring-like structures form.
