AbstractThe Center of Excellence in Materials Research and Innovation* (CEMRI) at the Yale University Center for Research on Innovative Structures and Phenomena (CRISP) discovers and develops novel engineered materials with emphasis on the unique opportunities that arise from designing man-made transition metal oxides at the atomic scale and from structuring amorphous metals down to nanometer dimensions. Two Interdisciplinary Research Groups (IRGs) lead the research effort. The Atomic Scale Design, Control, and Characterization of Oxide Structures IRG investigates the novel chemical, electronic, and magnetic properties that emerge at interfaces between oxides. The research addresses three grand challenges: the design of new oxides with unique physical properties; the creation of new devices based on the novel properties of oxide interfaces; and the understanding and manipulation of the interactions between electrons that give rise to novel properties. The Multi-Scale Surface Engineering with Metallic Glasses IRG focuses on the grand challenge of controlling surface properties of metals by structuring their surface topography over length scales of nanometers to centimeters. This IRG has the unique ability to pattern and shape metallic glasses using methods developed for plastics while retaining the superior properties of metals. Based on this capability, it aims to gain a fundamental understanding of the behavior of metallic glasses as they approach atomic length scales and then to devise hierarchical surface patterns (as often found in nature) to create unique properties. CRISP research impacts a wide range of technologies spanning computation, communication, energy, and medical applications. CRISP research is tightly integrated with an Education and Outreach (EO) program that leverages local EO successes in economically distressed, urban public schools that have a large population of students from underrepresented groups. There are two signature initiatives that evolve based on quantitative assessments. The first focuses on science, technology, engineering, and mathematics (STEM) recruitment and retention through professional development of teachers in order to impact the largest number of students. The second employs team-based research where the entire spectrum of STEM members (teachers, students, postdocs, and faculty) work together on multi-disciplinary IRG research projects. Collaborations with industry, national laboratories, and state and local governments play an important role in augmenting CRISP research and EO efforts and providing a pathway for broadening CRISP's impact. Key national laboratory collaborations enable joint development of new characterization methods at national user facilities. Industrial partners provide unique facilities, summer internships, and faculty development grants (e.g., IBM) as well as materials and processing equipment (e.g., PX Group). A partnership with the New Haven Public School system provides teacher assessment data used to develop and assess the impact of CRISP's teacher development initiatives. CRISP houses unique thin film growth and atomic-scale characterization and imaging tools that are not only essential to its success, but also provide a novel contribution to the national network of materials research facilities. The Center welcomes outside users to work with CRISP scientists on new research projects that take advantage of these unique capabilities.*An NSF Materials Research Science and Engineering Center (MRSEC)

摘要耶鲁大学创新结构与现象研究中心 (CRISP) 的材料研究与创新卓越中心* (CEMRI) 致力于发现和开发新型工程材料，重点关注在原子尺度设计人造过渡金属氧化物以及在纳米尺度构建非晶态金属所带来的独特机遇。两个跨学科研究小组 (IRG) 领导这项研究工作。氧化物结构的原子尺度设计、控制和表征 IRG 研究氧化物之间界面处出现的新型化学、电子和磁性特性。该研究解决了三大挑战：设计具有独特物理性能的新型氧化物；基于氧化物界面的新颖特性创建新器件；以及对电子之间相互作用的理解和操纵，从而产生新的特性。采用金属玻璃的多尺度表面工程 IRG 重点关注通过在纳米到厘米的长度尺度上构建金属表面形貌来控制金属表面特性的巨大挑战。该 IRG 具有独特的能力，可以使用为塑料开发的方法对金属玻璃进行图案化和成型，同时保留金属的卓越性能。基于这种能力，它的目标是对金属玻璃接近原子长度尺度时的行为有一个基本的了解，然后设计分层表面图案（如自然界中常见的那样）以创造独特的性能。 CRISP 研究影响了计算、通信、能源和医疗应用等广泛的技术。 CRISP 研究与教育和外展 (EO) 计划紧密结合，该计划利用当地 EO 在经济困难的城市公立学校取得的成功，这些学校有大量来自代表性不足的群体的学生。有两项标志性举措是基于定量评估而发展的。第一个重点是通过教师的专业发展来招聘和保留科学、技术、工程和数学（STEM），以影响最大数量的学生。第二种采用基于团队的研究，所有 STEM 成员（教师、学生、博士后和教师）共同开展多学科 IRG 研究项目。 与行业、国家实验室以及州和地方政府的合作在增强 CRISP 研究和 EO 工作以及为扩大 CRISP 影响提供途径方面发挥着重要作用。重要的国家实验室合作使得国家用户设施能够联合开发新的表征方法。工业合作伙伴提供独特的设施、暑期实习和教师发展补助金（例如 IBM）以及材料和加工设备（例如 PX Group）。与纽黑文公立学校系统的合作提供了教师评估数据，用于制定和评估 CRISP 教师发展计划的影响。 CRISP 拥有独特的薄膜生长和原子级表征和成像工具，这些工具不仅对其成功至关重要，而且还为国家材料研究设施网络做出了新颖的贡献。该中心欢迎外部用户与 CRISP 科学家合作，开展利用这些独特功能的新研究项目。*NSF 材料研究科学与工程中心 (MRSEC)
