U.S.-Korea Cooperative Research on Structural, Electronic and Magnetic Properties of Bulk Solids, Surfaces and Interfaces

美国西北大学物理系Arthur J. Freeman博士将与仁荷大学物理系Jae Il Lee博士、蔚山大学物理系Soon Cheol Hong博士、浦项工业大学物理系Byung Il Min博士进行为期24个月的研究。一个合作研究大块固体、表面和界面的结构、电子和磁性质的项目。在这个项目中，这些科学家将使用他们过去合作的新开发的计算方法/算法。使用这些计算方法将共同研究广泛的现象，包括金属、半导体、绝缘体及其化合物、覆盖层和超晶格的结构、电子和磁性。这项研究是基于这样一个假设，即固体材料的宏观样品的性质与该材料的单个分子和原子构建块的电子结构有关，并且可以从这些电子结构中推导出来。使用高度复杂的、完全自洽的局部密度计算机代码来计算这些材料的电子结构，在物理和化学性质和现象的预测方面取得了高度的可靠性。广泛的现象将被研究。应用包括理解新的金属间化合物和人造材料的性质和设计。合作者是本研究领域备受尊敬的科学家。他们过去的合作对这一领域的文献做出了重大贡献。该项目将为PI与（美国）多机构材料研究小组在材料磁性方面的工作提供宝贵的支持。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学工程财团（KOSEF）的支持。

This award provides funds to permit Dr. Arthur J. Freeman, Department of Physics, Northwestern University, to pursue with Dr. Jae Il Lee, Department of Physics, Inha University, Dr. Soon Cheol Hong, Department of Physics, University of Ulsan, and Dr. Byung Il Min, Department of Physics, Pohang Institute of Science and Technology (POSTECH), for 24 months, a program of cooperative research on structural, electronic, and magnetic properties of bulk solids, surfaces, and interfaces. In this project, these scientists will use newly developed computational methods/algorithms which are the product of their past collaboration. A wide range of phenomena will be investigated jointly using these computational methods, including the structural, electronic, and magnetic properties of metals, semiconductors, insulators, and their compounds, overlays, and superlattices. This research is based on the assumption that the properties of macroscopic samples of solid material are related to and can be derived from the electronic structure of individual molecules and atomic building blocks of that material. A high degree of reliability concerning predictions of physical and chemical properties and phenomena has been achieved using highly sophisticated, fully self-consistent local density computer codes for the calculation of electronic structures of these materials. A wide range of phenomena will be investigated. Applications include understanding the properties and design of new intermetallic compounds and artificial materials. The collaborators are highly respected scientists in the field of this research. Their past collaboration has resulted in significant contributions to the literature of this field. This project will provide valuable support for the PI's work with the (U.S.) multi-institutional Materials Research Group on the Magnetic Properties of Materials. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF).
