Clark Atlanta University (CAU), a research intensive university and Spelman College (SC) are two of the four institutions that comprise the Atlanta University Center (AUC), the nation’s oldest and largest consortium of Historically Black Colleges and Universities. Both institutions comprised a combined enrollment of over 6,500 students, over 95 % of whom are African Americans, a large portion of whom are first-generation college students. The proposed Partnership for Research and Education in Materials (PREM) between these two AUC schools and the Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM), a National Science Foundation-funded Materials Innovation Platform at Cornell University, will promote and enhance the participation and advance degree attainment of over 10 Ph.D. and over 40 B.S. students, most of whom will be from underrepresented minority groups. Students will develop expertise in the design and creation of new interface materials - materials that do not exist in nature - with unprecedented properties for the next generation of electronic, magnetoelectronic and optoelectronic devices, while acquiring a strong set of multidisciplinary skills in fundamental research. The participating students will conduct research at the three academic institutions and will be mentored by faculty from several disciplines. This PREM project will allow CAU and Spelman College to significantly accelerate their emergence in materials research and develop a long-lasting collaborative partnership with PARADIM. The research results under the CAU-SC-PARADIM PREM will be disseminated in peer-reviewed journals and conferences, and to the public at large via a dedicated web portal.A synergistic interdisciplinary research approach to the advancement of the basic understanding of oxide-oxide, oxide-covalent organic frameworks, and oxide-polymer interfaces that is essental for the design and creation of new interface materials with unprecedented properties for the next generation of electronic, magnetoelectronic and optoelectronic devices will be conducted. The PREM team will focus on the following key fundamental aspects of interface materials research: (1) theoretical calculations to predict mechanisms and guide the design of new oxide-oxide interface materials that enable electrical control of magnetism to achieve higher magnetoelectric coefficients at room temperature; (2) theoretical calculations, design and synthesis of ferromagnetic oxide/covalent organic framework COF van der Waals heterostructures and probing proximity-induced interlayer interactions, such as interlayer electronic coupling, and hybridization-induced charge delocalization on the COF layer formation; and (3) synthesis and electroconductive properties investigation of novel ferroelectric polymers/ferroelectric oxide interfaces. The researchers and world-class instrument facilities at PARADIM will enable and catalyze the exploration of the basic science of interface materials and provide unique opportunities for cross-fertilization of ideas, mentoring, and multidisciplinary training. The collaborative team will foster a high-level of research intensity and a student-centered environment by holding research-focus group meetings via video teleconferencing, academic year research, summer school and REU, and site visits, where students, post-docs, and faculty, are immersed in seminars and hands-on workshops to learn techniques in interface materials design, synthesis and characterization. Ultimately, this partnership will increase understanding of the structure-properties relationships of interface materials and pave the way for the next generation of oxide-based electronic materials.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.

克拉克亚特兰大大学（CAU）是一所研究型大学，斯佩尔曼学院（SC）是组成亚特兰大大学中心（AUC）的四所机构中的两所，亚特兰大大学中心是美国历史最悠久、规模最大的历史悠久的黑人学院和大学联盟。这两所大学共有6500多名学生，其中95%以上是非洲裔美国人，其中很大一部分是第一代大学生。这两所AUC学院和康奈尔大学加速实现、分析和发现界面材料平台（paradigm）之间拟议的材料研究和教育合作伙伴关系（PREM），将促进和加强10多名博士和40多名学士的参与和学位的提高，其中大多数将来自代表性不足的少数群体。学生将在设计和创造新的界面材料（自然界中不存在的材料）方面发展专业知识，这些材料具有下一代电子、磁电子和光电子器件前所未有的特性，同时在基础研究方面获得一套强大的多学科技能。参与的学生将在这三所学术机构进行研究，并将受到来自多个学科的教师的指导。这个PREM项目将使CAU和斯佩尔曼学院大大加快他们在材料研究方面的发展，并与PARADIM建立长期的合作伙伴关系。在cac - sc - paradigm PREM下的研究成果将在同行评议的期刊和会议上传播，并通过专门的门户网站向广大公众传播。一种协同的跨学科研究方法将推进对氧化物-氧化物、氧化物-共价有机框架和氧化物-聚合物界面的基本理解，这对于设计和创造具有下一代电子、磁电子和光电子器件前所未有性能的新界面材料至关重要。PREM团队将专注于界面材料研究的以下关键基础方面：(1)理论计算预测机制并指导新型氧化物-氧化物界面材料的设计，使磁性的电气控制能够在室温下实现更高的磁电系数；(2)理论计算、设计和合成铁磁氧化物/共价有机框架COF的范德华异质结构，并探测邻近诱导的层间相互作用，如层间电子耦合、杂化诱导的电荷离域对COF层形成的影响；(3)新型铁电聚合物/铁电氧化物界面的合成及导电性能研究。PARADIM的研究人员和世界一流的仪器设备将促进界面材料基础科学的探索，并为思想交流、指导和多学科培训提供独特的机会。合作团队将通过视频电话会议、学年研究、暑期学校和REU以及实地考察等方式举行研究焦点小组会议，培养高水平的研究强度和以学生为中心的环境，学生、博士后和教师将沉浸在研讨会和实践研讨会中，学习界面材料设计、合成和表征方面的技术。最终，这种合作关系将增加对界面材料结构-性能关系的理解，并为下一代氧化物基电子材料铺平道路。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
