Non-Technical Description: The Two-Dimensional Crystal Consortium (2DCC) is a Materials Innovation Platform, an NSF mid-scale infrastructure program in the Division of Materials Research, that is focused on advancing the synthesis and characterization of 2D materials. 2D materials are atomically thin layers that, due to the restricted electron and atom motion, have physical characteristics that are not present in three dimensions and hold the potential for revolutionary device technologies ranging from flexible electronics to quantum computing. The full realization of this potential requires atomic-level mastery over the synthesis of wafer-scale films and bulk crystals with high crystalline perfection and also the discovery of new material compositions and structures. The 2DCC focuses on advancing the synthesis science of 2D materials through the development of state-of-the-art experimental and computational tools and techniques for thin film deposition and bulk crystal growth supported by advanced characterization and processing. A facility-wide data management system captures and curates sample data with additional functionality to enable new modes of data-enabled research. An in-house team of researchers works collaboratively with external users to accelerate discovery of new materials, to develop processes for synthesis of large area 2D films to transition toward commercialization, and to disseminate knowledge, samples, data, and techniques within a national user facility that acts as a hub for scientific training and cross-fertilization. Outreach and training activities targeted at users and the broader 2D community include webinars, an annual workshop on 2D materials, on-line tutorials and a data science workshop. The 2DCC engages the materials research community across academia, industry and government laboratories across career stages, including students and faculty at minority serving or primarily undergraduate institutions. On-site training opportunities are targeted at developing the next generation of crystal growers and tool developers and broadening participation in synthesis and advanced characterization.Technical Description: The development of quantum materials in recent decades has led to transformative discoveries of emergent phenomena resulting from the interplay of reduced dimensionality, confinement, topology, and interactions. Two-dimensional layered chalcogenides (2DLC) are a prime example of this class of materials, encompassing van der Waals heterojunctions, topological insulators, topological semimetals, and high-temperature Fe-chalcogenide superconductors. The 2D Crystal Consortium (2DCC), an NSF Materials Innovation Platform, is motivated by the potential of 2DLCs for new physics and high-impact technologies tempered by the significant challenges associated with their synthesis. The Platform exploits 2DCC in-house expertise in materials growth by molecular beam epitaxy, metalorganic chemical vapor deposition, confinement heteroepitaxy, modeling of materials growth kinetics and sample properties, and bulk crystal growth. New synthesis capabilities include double-crucible Bridgman methods that target extreme stoichiometric precision and an integrated plasma/evaporation tool for scalable synthesis of air-stable 2D polar metals. This synthesis web is interconnected with a comprehensive suite of advanced spectroscopy, scanning probe and processing tools allowing sample exchange while maintaining vacuum or inert-gas environments. Data generated throughout the facility feeds into a sample data tracking system that embeds knowledge graph functionality to enable new modes of data-enabled materials discovery. Theory and computational tools are deployed in a tightly integrated theory-computation-measurement-synthesis loop that targets the understanding of both key kinetic growth processes and the results of in situ and ex situ characterization, following the vision of the Materials Genome Initiative.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术描述：二维晶体联盟（2DCC）是材料创新平台，这是NSF材料研究部中的NSF中尺度基础设施计划，其重点是推进2D材料的合成和表征。 2D材料在原子上是薄的层，由于电子和原子运动的受限，其物理特性在三个维度上不存在，并且具有从柔性电子设备到量子计算的革命性设备技术的潜力。这种潜力的全部实现需要对具有高晶体完美的晶圆尺度膜和散装晶体的合成以及发现新的材料组成和结构的合成。 2DCC着重于通过开发薄膜沉积和薄膜沉积和大量晶体生长的最先进的实验和计算工具和技术来推进2D材料的合成科学，并由先进的表征和加工支持。设施范围内的数据管理系统捕获并策划样本数据具有其他功能，以实现新的支持数据的研究模式。一组内部研究人员与外部用户合作，以​​加速发现新材料，开发合成大面积2D电影以过渡到商业化的过程，并在国家用户设施中传播知识，样本，数据和技术，该工具是作为科学培训和交叉提供的枢纽。针对用户和更广泛的2D社区的推广和培训活动包括网络研讨会，2D材料，在线教程和数据科学研讨会的年度研讨会。 2DCC与各个职业阶段的学术界，工业和政府实验室之间的材料研究界参与，包括少数派服务或主要是本科机构的学生和教职员工。现场培训机会的目标是开发下一代水晶种植者和工具开发人员，并扩大参与合成和高级表征。技术描述：近几十年来的量子材料的开发导致了由于降低的维度，约束，约束，拓扑和互动而导致的新兴现象的变革性发现。二维分层硫化盐（2DLC）是此类材料的一个典型例子，包括范德华的杂音杂音，拓扑绝缘子，拓扑半学和高温Fe-Chalcogenide超导管器。 NSF材料创新平台2D晶体联盟（2DCC）是由2DLCs对新物理学和高影响力技术的潜力所激发的，并受到与其合成相关的重大挑战所缓解的。该平台通过分子束外延，金属有机化学蒸气沉积，限制异孕，材料生长动力学和样品特性的建模以及大量晶体生长来利用2DCC内部材料内部专业知识。新的合成功能包括双重挑剔的Bridgman方法，该方法针对极端化学计量精度和集成的等离子体/蒸发工具，用于可扩展的空气稳定2D极性金属。该综合网络与综合的高级光谱，扫描探针和处理工具相互联系，允许在维持真空或惰性气体环境的同时样品交换。在整个设施中生成的数据都将馈送到示例数据跟踪系统中，该数据跟踪系统嵌入了知识图功能，以实现新的启用数据材料的模式。理论和计算工具以紧密整合的理论与计算合成循环的形式部署，该循环的目标是对关键动力学增长过程的理解以及原位和现场表征的结果，遵循材料基因组启动的愿景，这是NSF的法定任务，反映了NSF的法定范围，并通过评估了构成的构成群体，并反映了构成群体的支持。
