The Center of Excellence in Materials Research and Innovation* (CEMRI) at the Cornell Center for Materials Research (CCMR) will explore fundamental challenges in interdisciplinary materials research that will enable technological progress of a scope and complexity that requires the sustained contribution of researchers from multiple disciplines. In doing so, the Center will develop the experimental and theoretical tools and techniques necessary for further advances. Research in the Center will be pursued through three Interdisciplinary Research Groups (IRGs) as well as a number of smaller Seed research projects. The theme of IRG-1 is to understand and control complex electronic materials that have spectacular electronic and magnetic properties, including high temperature superconductivity, huge electric field effects, and many forms of nanoscale electron self-organization. Starting from materials that are reasonably well described by existing theory, the group will systematically perturb the targeted materials through experimentally-accessible parameters such as electron overlap and carrier density, using observed changes in materials properties to drive new advances in understanding. The goal of IRG-2 is to understand and apply new mechanisms to manipulate electron spins in both ferromagnetic and non-ferromagnetic materials. This research will potentially enable nonvolatile magnetic memory technologies that are much smaller, more energy efficient, more reliable, faster, and less expensive than competing strategies, possibly leading to the replacement of silicon-based memories in many applications. IRG-3 will explore atomic membranes an exciting new class of two-dimensional, free-standing materials only one atom thick yet mechanically robust, chemically stable, and virtually impermeable. Applications for these membranes loom in almost every technological sector from electronics to chemical passivation to high-resolution imaging, but major materials challenges must first be addressed. The timely exploration of novel ideas, higher-risk and potentially transformative projects will be enabled by a Seed research program that will pursue limited-term, exploratory research projects. This program will nucleate new interdisciplinary, materials-focused research projects, integrate new faculty into the Center, and refresh the Center's portfolio of research. National and international collaborations will augment and enable the Center's research by providing access to one-of-a-kind facilities, specialized instrumentation, new techniques, and world-leading expertise.The research program will educate a diverse cadre of undergraduates, graduate students, and postdoctoral scholars in areas of national need and importance. To further improve the national supply of science and engineering students, Center researchers will partner with K-12 teachers to improve student interest and achievement in science, technology, and mathematics. These activities will be complemented by a summer research program that will provide undergraduate students with an introduction to materials research. The Center will enhance the local and national materials research infrastructure by offering both routine and state-of-the-art Shared Facilities, offering fabrication, analysis, and characterization and consultation to all users (on a fee-per-use basis). Knowledge transfer to industry and other sectors will be stimulated by extensive collaborations with international, industrial, academic, and national lab researchers, as well as by a multifaceted industrial partnerships program.* An NSF Materials Research Science and Engineering Center (MRSEC)

康奈尔大学材料研究中心（CCMR）的材料研究与创新卓越中心（CEMRI）将探索跨学科材料研究中的基本挑战，这些挑战将使技术进步的范围和复杂性需要来自多个学科的研究人员的持续贡献。在此过程中，该中心将开发进一步发展所需的实验和理论工具和技术。该中心的研究将通过三个跨学科研究小组（IRG）以及一些较小的种子研究项目进行。IRG-1的主题是理解和控制具有壮观的电子和磁性的复杂电子材料，包括高温超导性，巨大的电场效应和许多形式的纳米级电子自组织。从现有理论合理描述的材料开始，该小组将通过实验可获得的参数（如电子重叠和载流子密度）系统地扰动目标材料，利用观察到的材料特性变化来推动理解的新进展。IRG-2的目标是理解和应用新的机制来操纵铁磁和非铁磁材料中的电子自旋。这项研究将有可能实现比竞争策略更小、更节能、更可靠、更快且更便宜的非易失性磁性存储器技术，这可能会导致许多应用中硅基存储器的替代。IRG-3将探索原子膜，这是一种令人兴奋的新型二维独立材料，只有一个原子厚，但机械坚固，化学稳定，几乎不可渗透。这些膜的应用几乎出现在从电子到化学钝化再到高分辨率成像的每个技术领域，但必须首先解决主要的材料挑战。及时探索新的想法，高风险和潜在的变革性项目将通过种子研究计划来实现，该计划将追求有限的探索性研究项目。该计划将核心新的跨学科，材料为重点的研究项目，整合新的教师到中心，并刷新中心的研究组合。国家和国际合作将通过提供独一无二的设施、专业仪器、新技术和世界领先的专业知识来加强和促进中心的研究。研究计划将在国家需要和重要的领域培养多样化的本科生、研究生和博士后学者。为了进一步提高全国理工科学生的供应，中心研究人员将与K-12教师合作，以提高学生在科学，技术和数学方面的兴趣和成就。这些活动将通过夏季研究计划来补充，该计划将为本科生提供材料研究的介绍。该中心将通过提供常规和最先进的共享设施，为所有用户提供制造，分析，表征和咨询（按使用收费），加强当地和国家的材料研究基础设施。通过与国际、工业、学术和国家实验室研究人员的广泛合作，以及多方面的工业伙伴关系计划，将促进向工业和其他部门的知识转移。NSF材料研究科学与工程中心（MRSEC）
