MIP: Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM)

非技术描述：康奈尔大学领导一个材料创新平台，这是美国国家科学基金会材料研究部的一个中型基础设施项目。康奈尔大学与约翰霍普金斯大学合作，形成了界面材料加速实现、分析和发现(PARADIM)的平台。PARADIM是一家国家级用户设施，能够以更有效的方式进行材料研究：通过建立一个生态系统-一个全国性的从业者社区-来加速材料发现，该生态系统配备了实验和理论方法，使用户能够实现具有优越电子特性的无机材料。PARADIM的范围是以单晶和外延薄膜的形式实现具有优越电子特性的无机材料，重点是新的界面量子材料。PARADIM用户实现的无机材料要么是以前从未制造过的，要么是将以完美、纯净的方式制造出来的，或者是与有令人信服的理由相信将产生优异电子特性的其他材料相结合的。该平台的开放结构使所有美国科学家的材料发现民主化，并使用户能够集体应用材料基因组倡议的“闭环”方法。PARADIM还提供许多社区建设和培训部分，为未来的劳动力做好准备，包括两个每年为期一周的暑期课程，介绍逐个设计的材料方法，利用并向用户介绍PARADIM的设施和能力。技术描述：PARADIM为实现具有卓越电子特性的无机材料提供一套先进的公开可用的设备和专业知识。PARADIM最先进的设施包括(1)主要的晶体生长方法，特别是光学浮区技术；(2)全自动分子束外延系统，用户可以从元素周期表的62种元素中进行选择，并通过角度分辨光电子能谱看到他们产生的材料的电子结构；(3)先进的电子显微镜，用于探测材料的结构、化学和功能性质，精确到原子尺度；(4)人工智能/机器学习方法，利用现有和新材料数据提取可操作的信息，并帮助用户实时实现材料认识；(5)帮助设计和理解材料以及分析实验数据的理论能力，以及(6)培训用户如何最大限度地利用这些能力并改进这些工具的人才团队。PARADIM的内部研究范围是编织具有通过将不同的量子材料缠绕在一起而产生的量身定制功能的新的“量子织物”。许多新的量子技术要求材料具有块状化合物中通常不存在的性质，例如具有非阿贝尔统计的拓扑超导体或准粒子。这通常是因为这样的性质可能产生于通常可能在单一化合物中相互竞争的多个状态。通过将具有不同性质(如超导或磁性)的“线”编织在一起，PARADIM的内部团队旨在实现具有新型电子、磁性、拓扑或此类纹理的混合结构的量子织物，以及具有不存在于散装中并可能在未来量子技术中发挥重要作用的功能。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Non-Technical Description: Cornell University leads a Materials Innovation Platform, an NSF mid-scale infrastructure program in the Division of Materials Research. Cornell University, in partnership with Johns Hopkins University, forms the Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM). PARADIM is a national user facility enabling a more effective way of doing materials research: one that accelerates materials discovery by establishing an ecosystem - a national community of practitioners - that is equipped with experimental and theoretical methods to enable users to realize inorganic materials with superior electronic characteristics. The scope of PARADIM is the realization of inorganic materials with superior electronic characteristics in the form of single crystals and epitaxial thin films with an emphasis on new interface quantum materials. The inorganic materials realized by PARADIM users have either never been made before or are to be made with a perfection, purity, or interfacing with other materials for which there are compelling reasons to believe that superior electronic characteristics will result. The open structure of the Platform democratizes materials discovery for all U.S. scientists and makes it possible for users to collectively apply the "closed loop" approach of the Materials Genome Initiative. PARADIM also provides numerous community-building and training components to prepare the future workforce including two annual week-long summer schools on materials-by-design approaches leveraging and informing users about PARADIM's facilities and capabilities.Technical Description: PARADIM provides an advanced set of openly available equipment and expertise for the realization of inorganic materials with superior electronic characteristics. PARADIM's state-of-the-art facilities include (1) major crystal growth methods, especially optical floating-zone techniques; (2) a fully automated molecular-beam epitaxy system where users can select among 62 elements of the periodic table and see the electronic structure of the materials they produce by angle-resolved photoemission spectroscopy; (3) advanced electron microscopes for probing the structure, chemistry, and functional properties of materials down to the atomic scale; (4) artificial intelligence/machine learning approaches to leverage existing and new materials data to extract actionable information and aid users' materials realization in real-time; (5) theoretical capabilities to help design and understand materials as well as to analyze experimental data, and (6) a talented team who trains users how to make the most of these capabilities and improves these tools. The scope of the in-house research of PARADIM is to weave new "quantum fabrics" with tailored functionalities which arise by intertwining different quantum materials. Many new quantum technologies demand materials with properties that typically do not exist in bulk compounds, for instance, topological superconductors or quasiparticles with non-Abelian statistics. This is often because such properties may arise from multiple states that might normally be in competition with one another in a single compound. By weaving together "threads" with different properties, such as superconductivity or magnetism, PARADIM's in-house team aims to realize quantum fabrics with novel electronic, magnetic, topological, or a mixture of such textures and with functionalities that do not exist in bulk and could play an important role in future quantum technologies.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.
