Towards the Computational Design of Moir\'e Assemblies.

Two-dimensional (2D) layered materials, demonstrating significantly different properties from their bulk counterparts, offer a materials platform with potential applications from novel information processing to communication devices. Although some single- and few-layer forms of materials such as graphene and transition metal dichalcogenides have been realized and thoroughly studied, the space of arbitrarily layered assemblies is still mostly unexplored. We introduce concepts and methods for automated materials discovery and design, and use them to investigate trends in various low-dimensional moir\'e assemblies. Specifically, we use electronic structure calculations based on tight binding with agent-based simulation to explore the spaces of two-layer molybdenum disulfide, multi-layer graphene, and model one-dimensional moir\'e assemblies. This work more generally combines physics-based and data-driven modeling to demonstrate precise control of the electronic properties of layered materials through careful choice of the constituent layers, their stacking, and relative orientation, with important implications for the development of novel devices.
