Technical AbstractCornell University will lead a Materials Innovation Platform, a new NSF mid-scale instrumentation program supported in the Division of Materials Research. Cornell University, in partnership with Clark Atlanta University, Johns Hopkins University, and Princeton University form the Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM). PARADIM seeks to advance fundamental understanding of oxide-based hetero-interfaces with a range of two-dimensional (2D) material systems including oxides, chalcogenides and graphene through transformational research and mid-scale investments in instrumentation for bulk and thin film crystal growth and characterization. Fabricating interfaces and heterostructures between complex oxides and 2D materials allows for the creation of an atomically-precise "active substrate" that can itself have novel electronic and magnetic functionality, such as ferroelectricity, ferromagnetism, or superconductivity. Creating interface materials with designed properties opens up untold degrees of freedom that may result in transformational evolutions in next generation electronics.PARADIM's in-house research team will focus on developing hetero-interfaces that exhibit broken valley symmetry at interfaces between 2D materials and active substrates with novel electronic and magnetic functionality. External researchers from across the U.S. also working to advance the next generation of electronic devices; specifically those researching valleytronics, spintronics, and multiferroics; will also have access to the Platform's growth capabilities and the expertise in synthesis, characterization, and theoretical modeling. Along with access to mid-scale level tools and expertise, a unique feature of the Platform is the access to new oxide bulk single crystal samples and epitaxial thin film heterostructures produced and curated by PARADIM. Signature mid-scale instruments of the Platform include a suite of specialty bulk single crystal growth instruments with in-situ characterization tools capable of growing manganites, ferrites, cobaltates, nickelates, ruthenates, iridates and other compelling oxide systems. An MBE tool with unique in-situ diagnostic capabilities and a tandem MOCVD instrument for depositing non-oxide systems such as chalcogenides is also available. The combination of instruments allows for the growth of a wide variety of inorganic systems, yielding crystals for fundamental studies, novel heterostructures exhibiting novel properties, and bulk substrates on which to grow unexplored thin film phases and structures. In addition, the Platform makes available an impressive range of TEMs capable of high-throughput structural and chemical analysis as well as magnetic imaging and low-temperature spectroscopic mapping. The research of external users and those of the PARADIM in-house team together create a community of researchers poised to make transformational gains in the accelerated discovery and deployment of new electronic materials, specifically enabling new oxide bulk single crystals and novel heterostructures.Along with an annual REU program, PARADIM will offer hands-on research experiences for local undergraduates year-round in the crystal growth facilities. In addition, educational materials will be available to users of PARADIM in the form of on-line short courses as well as a Materials-by-Design Toolbox that provides open-source software and databases to users on-line. A signature outreach program will be the annual PARADIM Summer Schools, where graduate students, post-docs, young faculty, and industrial scientists are immersed in a seminar and hands-on workshop environment to learn techniques in bulk and thin film crystal growth, theory, and characterization. Workshops will also be held that are industry focused.http://www.paradim.cornell.edu Non-Technical AbstractThe Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM) will help users design and create new interface materials - materials that do not exist in nature - with unprecedented properties for the next generation of electronic devices. Creating new interface materials with unprecedented properties, by design rather than by serendipity, is accomplished in PARADIM through a synergistic set of user facilities dedicated to theory (figuring out where to put the atoms for useful behavior), synthesis (putting the atoms in the targeted positions), and characterization (seeing that the atoms are indeed in the desired positions). Each of these world-class user facilities is equipped with the latest tools, techniques, and expertise to realize this materials-by-design dream. Users from throughout the nation will use PARADIM to discover and create interface materials for the next generation of electronics and optoelectronics. These new materials will enable novel ways for electrons to carry information in solid-state devices and efficiently interact with magnetic, electrical, and optical stimuli. To balance the desire for a rich nation-wide user group and the practicality of managing physical resources across different locations, PARADIM locates its web-based theory user facility at Clark Atlanta University, its bulk crystal growth user facility at Johns Hopkins University, and its thin film growth and characterization user facilities at Cornell University. Researchers from Princeton University will participate in the in-house research activity. PARADIM's user facilities leverage existing user facilities including the Cornell NanoScale Facility, the Cornell Center for Materials Research, and the Johns Hopkins Materials Characterization and Processing Facility. In addition to training materials innovators to work effectively in teams, PARADIM will conduct free summer schools involving hands-on use of PARADIM facilities to help educate PARADIM's "community of practitioners" and advance the field through the cross-fertilization of ideas. PARADIM will also serve as a focal point for training the next generation of technologists - people who are accustomed to designing and creating new interface materials with atomic precision and have the skills necessary to capitalize on useful new interface material ideas and make them a reality. This platform marks the beginning of a new PARADIM in materials discovery.http://www.paradim.cornell.edu

康奈尔大学将领导一个材料创新平台，这是一个由美国国家科学基金会材料研究部支持的新的中等规模仪器项目。康奈尔大学与克拉克亚特兰大大学、约翰霍普金斯大学和普林斯顿大学合作，建立了加速实现、分析和发现界面材料的平台（paradigm）。PARADIM旨在通过转化研究和对体和薄膜晶体生长和表征仪器的中等规模投资，通过一系列二维（2D）材料系统（包括氧化物、硫族化合物和石墨烯）推进对基于氧化物的异质界面的基本理解。在复杂氧化物和二维材料之间制造界面和异质结构，可以创造出原子精确的“活性衬底”，它本身具有新颖的电子和磁性功能，如铁电性、铁磁性或超导性。创造具有设计属性的界面材料开辟了无数的自由度，可能会导致下一代电子产品的转型演变。PARADIM的内部研究团队将专注于开发异质界面，在具有新型电子和磁性功能的二维材料和有源衬底之间的界面上表现出破谷对称性。来自美国各地的外部研究人员也在努力推进下一代电子设备；特别是那些研究谷电子学、自旋电子学和多铁学的人；还将获得该平台的增长能力以及合成、表征和理论建模方面的专业知识。除了获得中等规模的工具和专业知识外，该平台的一个独特之处在于可以获得PARADIM生产和策划的新型氧化体单晶样品和外延薄膜异质结构。该平台的标志性中等规模仪器包括一套具有原位表征工具的特种大块单晶生长仪器，能够生长锰酸盐、铁氧体、钴酸盐、镍酸盐、钌酸盐、铱酸盐和其他引人注目的氧化物体系。此外，还可以使用具有独特原位诊断能力的MBE工具和用于沉积非氧化物体系（如硫族化物）的串联MOCVD仪器。仪器的组合允许生长各种各样的无机系统，产生用于基础研究的晶体，具有新特性的新型异质结构，以及用于生长未开发的薄膜相和结构的大块衬底。此外，该平台还提供了一系列令人印象深刻的tem，能够进行高通量结构和化学分析，以及磁成像和低温光谱制图。外部用户的研究和PARADIM内部团队的研究共同创建了一个研究人员社区，准备在加速发现和部署新的电子材料方面取得变革性的成果，特别是实现新的氧化体单晶和新的异质结构。与年度REU计划一起，PARADIM将为当地本科生提供全年在晶体生长设施中的实践研究经验。此外，将以联机短期课程的形式向paradigm的用户提供教育材料，以及向联机用户提供开放源码软件和数据库的按设计材料工具箱。一个标志性的拓展项目将是一年一度的PARADIM暑期学校，研究生、博士后、年轻教师和工业科学家将沉浸在研讨会和实践车间环境中，学习体和薄膜晶体生长、理论和表征的技术。http://www.paradim.cornell.edu非技术摘要界面材料加速实现、分析和发现平台（PARADIM）将帮助用户设计和创造新的界面材料-自然界中不存在的材料-具有下一代电子设备前所未有的特性。通过设计而不是偶然的机会，在PARADIM中创建具有前所未有属性的新界面材料，这是通过一组协同的用户工具来完成的，这些工具专门用于理论（找出将原子放置在有用行为的位置）、合成（将原子放置在目标位置）和表征（看到原子确实处于所需位置）。这些世界级的用户设施都配备了最新的工具、技术和专业知识，以实现这一设计材料的梦想。来自全国各地的用户将使用PARADIM来发现和创造下一代电子和光电子的界面材料。这些新材料将为电子在固态器件中携带信息提供新的途径，并有效地与磁、电和光刺激相互作用。为了平衡对丰富的全国用户群的渴望和跨不同地点管理物理资源的实用性，paradam将其基于网络的理论用户设施设在克拉克亚特兰大大学，将其大块晶体生长用户设施设在约翰霍普金斯大学，将其薄膜生长和表征用户设施设在康奈尔大学。普林斯顿大学的研究人员将参与内部研究活动。PARADIM的用户设施利用现有的用户设施，包括康奈尔纳米设施、康奈尔材料研究中心和约翰霍普金斯材料表征和加工设施。除了培训材料革新者有效地在团队中工作外，PARADIM还将举办免费的暑期学校，包括亲身使用PARADIM的设施，以帮助教育PARADIM的“从业者社区”，并通过思想的交流促进该领域的发展。PARADIM还将作为培训下一代技术人员的焦点，这些技术人员习惯于以原子精度设计和创造新的界面材料，并具有利用有用的新界面材料想法并使其成为现实所需的技能。这个平台标志着材料发现新范式的开始。http://www.paradim.cornell.edu
