LAN --2D分层组件的材料符号
LAN -- A materials notation for 2D layered assemblies
摘要：
二维（2D）层状材料为新的物理和应用提供了有趣的可能性。在试图以系统的方式探索材料空间之前，或者结合理论，计算和实验的见解，需要对关于任意组成的集合体的信息进行正式描述。在这里，我们介绍了一个域通用符号，用于描述从单层到任意组成的扭曲组件，存在或尚未制造的二维分层材料的空间。该符号对应于分层结构的逐步组装的理论材料概念，该分层结构使用一系列旋转、垂直堆叠和对单个2D层的其他操作。它的范围是证明了一些使用常见的单层材料作为构建块的示例结构。这项工作的总体目标是有助于系统的编纂，捕获和转让材料知识的二维分层材料领域。
英文摘要：
Two-dimensional (2D) layered materials offer intriguing possibilities for novel physics and applications. Before any attempt at exploring the materials space in a systematic fashion, or combining insights from theory, computation and experiment, a formal description of information about an assembly of arbitrary composition is required. Here, we introduce a domain-generic notation that is used to describe the space of 2D layered materials from monolayers to twisted assemblies of arbitrary composition, existent or not-yet-fabricated. The notation corresponds to a theoretical materials concept of stepwise assembly of layered structures using a sequence of rotation, vertical stacking, and other operations on individual 2D layers. Its scope is demonstrated with a number of example structures using common single-layer materials as building blocks. This work overall aims to contribute to the systematic codification, capture and transfer of materials knowledge in the area of 2D layered materials.
