Center for Emergent Materials

俄亥俄州立大学(OSU)材料研究科学与工程中心(MRSEC)，名为应急材料中心(CEM)，对磁性电子学中的应急材料和现象进行综合研究。该中心研究活动的目的是促进对紧急材料和现象的了解，并开发研究它们所需的高度复杂的实验和理论工具，这将为建造未来可以执行多种功能的基于氧化物的电子设备以及具有集成存储器和逻辑的高能效、快速的计算机奠定科学基础。该中心有两个跨学科研究小组(IRGS)。IRG 1，朝向自旋保持的、非均匀的自旋网络，将发展对低维、自旋保持的材料(如硅和碳)中的电子-自旋注入和输运的新理解。这一认识为创造用于下一代计算的新型高密度自旋网络提供了新的材料基础。IRG 2，双钙钛矿界面和异质结构，通过对界面结构、缺陷和磁输运性质的了解，设计和控制创新的双钙钛矿异质结构的多功能特性。这种对金属氧化物磁性的新知识使基于氧化物的电子学这一新兴领域取得了重大进展。与IRGS相辅相成的是种子资助计划，该计划为CEM提供了必要的灵活性和活力，使其能够迅速有效地应对快速变化的材料研究格局。与研究活动相结合，CEM加强了课堂教育，创造了研究实习机会，拓宽了科学-技术-工程-数学(STEM)的“管道”，并增强了STEM的多样性。活动包括旨在认知材料科学概念的创新教育研究计划，K-12外展和访问计划，本科生研究计划，以及研究生教育强化计划。多学科的俄亥俄州立大学材料社区已经拥有主要的世界级共享实验设施，这些设施被用于CEM研究和教育。该中心与电子、存储和仪器仪表行业、国家实验室和研究所、其他美国大学以及中国、印度、德国和英国的国际大学和实验室合作。

The Materials Research Science and Engineering Center (MRSEC) at the Ohio State University (OSU), titled Center for Emergent Materials (CEM), performs integrated research on emergent materials and phenomena in magnetoelectronics. The aim of the Center research activities is to advance understanding of the emergent materials and phenomena and to develop highly sophisticated experimental and theoretical tools required to study them, which will lay down the scientific foundation for building future oxide-based electronic devices that can perform multiple functions, and energy-efficient, fast computers that have integrated memory and logic. The Center has two interdisciplinary research groups (IRGs). IRG 1, Towards Spin-Preserving, Heterogeneous Spin Networks, will develop a new understanding of electron-spin injection and transport in low-dimensional, spin-preserving materials such as silicon and carbon. This understanding provides a new materials basis for creating novel high-density spin networks for next-generation computing. IRG 2, Double Perovskite Interfaces and Heterostructures, designs and controls multifunctional properties of innovative double perovskite heterostructures through the understanding of structure, defects, and magnetotransport properties at interfaces. This new knowledge of magnetism in metallic oxides enables important advances in the emerging field of oxide-based electronics. The IRGs are complemented by a Seed Funding program, which provides the necessary flexibility and vitality to CEM in responding swiftly and effectively to the rapidly-changing materials research landscape. Integrated with the research activities, CEM enhances classroom education, creates research internship opportunities, widens the Science-Technology-Engineering-Math (STEM) "pipeline," and enhances diversity in STEM. Activities include an innovative education research program aimed at cognition of materials science concepts, K-12 outreach and visitation programs, undergraduate research programs, and graduate-education enhancement programs. The multidisciplinary OSU materials community is already home to major world-class shared experimental facilities, which are brought to bear on CEM research and education. The Center collaborates with the electronics, storage, and instrumentation industries; national laboratories and institutes; other U.S. universities; and international universities and laboratories in China, India, Germany, and United Kingdom.
