any substrate efficiently. The method named “solution epitaxy” involves two steps. The first is to self‐assemble micrometer‐sized 2DCOS on water surface. The second is epitaxial growth of them into millimeter or centimeter sized 2DCOS with thickness of several molecular layers. The general applicability of this method for the growth of 2DCOS is demonstrated by nine organic semiconductors with different
有机半导体的二维(2D)晶体(2DCOS)引起了大面积且低成本的柔性光电技术的关注。但是,以可控的方式生长大型2DCOS并将其转移到具有技术重要性的基板上仍然是关键挑战。本文中,我们报告了一种简便,通用且有效的方法,可以将2DCOS生长到厘米大小,可以有效地将其转移到任何基材上。名为“溶液外延”的方法涉及两个步骤。首先是在
水面上自组装微米级的2DCOS。第二个是将它们外延生长为毫米或厘米大小的2DCOS,厚度为几个分子层。九种具有不同分子结构的有机半导体证明了该方法在2DCOS生长中的普遍适用性。
