U.S.-Japan Collaborative Project in Quantum Transitions in Nanostructures

9321727 MERZ美日纳米结构量子跃迁合作项目这是美国国家科学基金会量化电子结构中心(QUEST)、加州大学圣巴巴拉分校和东京大学的合作项目。该项目的日本部分得到了日本研究开发公司(JRDC)的支持。主要研究人员是中心主任詹姆斯·L·默茨和东京大学的佐木博之教授。通过人员交流，特别是博士后研究员和高级研究人员的交流，两个小组将在四个不同但相关的实验领域开展研究，致力于覆盖这四个领域的量子跃迁基础理论：(1)量子井、量子线和其他纳米结构中的光学和远红外跃迁及其红外和光导响应；(2)涉及电子和/或空穴的驰豫和散射过程，包括量子态内和量子态之间的电子和/或空穴；(3)周期合金及其在量子阱中合金成分的波动，包括它们对光学和电子跃迁的影响；以及(4)新型纳米结构形成的先进生长和加工技术和材料科学，重点是生长结构和表面的原位研究，以扩大纳米结构完善的可控性。预计该项目将产生大量关于生长过程和由该生长过程产生的表面性质的新的重要信息。***

9321727 Merz U.S.-Japan Collaborative Project in Quantum Transitions in Nanostructures This is a cooperative project between the NSF Center for Quantized Electronic Structures (QUEST), University of California, Santa Barbara and the University of Tokyo. The Japanese portion of the project is supported by the Research Development Corporation of Japan (JRDC). The principal investigators are James L. Merz, Center Director, and Professor Hiroyuki Sakaki, University of Tokyo. Through an exchange of personnel, specifically postdoctoral fellows and senior investigators, the two groups will carry out research in four different but related experimental areas, with an effort in fundamental theory of quantum transitions overlaying these four areas: (1) optical and far infrared transitions in quantum wells, quantum wires, and other nanostructures, and their infrared and photo-conductive responses; (2) relaxation and scattering processes involving electrons and/or holes, both within the quantum states and between them; (3) periodic alloys and their fluctuations of alloy composition in quantum wells, including their effect on optical and electronic transitions; and (4) advanced growth and processing technology and material science for novel nanostructure formation, with emphasis on the in-situ study of grown structures and surfaces to expand the controllability of the perfection of nanostructures. It is expected that the project will generate considerable new and important information concerning both the growth process and the nature of the surfaces that result from this growth process. ***
