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) 是一个材料创新平台，是 NSF 材料研究部的中型基础设施计划，专注于推进 2D 材料的合成和表征。二维材料是原子薄层，由于电子和原子运动受限，具有三维中不存在的物理特性，并且具有从柔性电子到量子计算等革命性设备技术的潜力。要充分实现这一潜力，需要在原子水平上掌握晶圆级薄膜和具有高晶体完美度的块状晶体的合成，并发现新的材料成分和结构。 2DCC 致力于通过开发最先进的薄膜沉积和块状晶体生长实验和计算工具及技术，并在先进的表征和处理的支持下，推进 2D 材料的合成科学。设施范围内的数据管理系统可捕获和整理具有附加功能的样本数据，以实现数据支持的新研究模式。内部研究团队与外部用户合作，加速新材料的发现，开发大面积二维薄膜的合成工艺以向商业化过渡，并在作为科学培训和交叉授精中心的国家用户设施内传播知识、样本、数据和技术。针对用户和更广泛的 2D 社区的外展和培训活动包括网络研讨会、2D 材料年度研讨会、在线教程和数据科学研讨会。 2DCC 吸引了跨职业阶段的学术界、工业界和政府实验室的材料研究界，包括少数族裔服务机构或主要是本科院校的学生和教师。现场培训机会旨在培养下一代晶体生长者和工具开发人员，并扩大合成和高级表征的参与。技术描述：近几十年来量子材料的发展导致了对降维、限制、拓扑和相互作用的相互作用所产生的新兴现象的变革性发现。二维层状硫族化物 (2DLC) 是此类材料的一个主要例子，包括范德华异质结、拓扑绝缘体、拓扑半金属和高温铁硫族化物超导体。 2D 晶体联盟 (2DCC) 是 NSF 材料创新平台，其动机是 2DLC 在新物理和高影响力技术方面的潜力，但由于其合成相关的重大挑战而受到影响。该平台利用 2DCC 在材料生长方面的内部专业知识，包括分子束外延、金属有机化学气相沉积、限制异质外延、材料生长动力学和样品特性建模以及块状晶体生长。新的合成能力包括以极端化学计量精度为目标的双坩埚布里奇曼方法，以及用于可扩展合成空气稳定的二维极性金属的集成等离子体/蒸发工具。该合成网络与一整套先进的光谱学、扫描探针和处理工具互连，允许样品交换，同时保持真空或惰性气体环境。整个设施生成的数据会输入样本数据跟踪系统，该系统嵌入知识图功能，以实现基于数据的材料发现的新模式。理论和计算工具被部署在一个紧密集成的理论-计算-测量-合成循环中，其目标是理解关键的动力学生长过程以及原位和异位表征的结果，遵循材料基因组计划的愿景。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
