PIRE: U.S.-Japan Cooperative Research & Education: Ultrafast and Nonlinear Optics in 6.1-Angstrom Semiconductors

OISE-0530220(河野纯一郎，威廉·马什·赖斯大学)《帝国：美日合作研究与教育：6.1埃半导体中的超快和非线性光学》河野纯一郎领导的国际研究和教育伙伴关系，研究基于6.1埃半导体(InAs，GaSb，AlSb)的量子结构的超快和非线性光学性质。这些半导体几乎是晶格匹配的(晶格常数约为6.1A)，可以外延生长形成异质结构。尽管它们在下一代器件中具有很好的应用前景，但对它们的光学性质，特别是在时间域和高激光强度下的光学性质，还很少有人探索。各种光学光谱方法将被用来研究电荷和自旋动力学。这类研究不仅有望增加对相互作用电子的状态和动力学的了解，而且还将为哪些结构最适合具体应用提供新的见解。该项目建立了美国莱斯大学、佛罗里达大学和德克萨斯农工大学与日本大阪理工学院和东京理工学院之间的长期合作伙伴关系。这一国际合作伙伴关系侧重于双方研究优势的互补，日本合作者提供独特的材料生长和加工能力。该项目还包括一个针对处于不同学术生涯阶段的学生的分级教育活动计划，以吸引年轻人进入新兴的电气工程和物理科学领域，特别是纳米技术。教育活动的基石将是为美国大学的研究生和本科生在日本进行为期10周的学习和研究实习计划。一年一度的创新美国-纳米技术研讨会将为回到美国的学生加强日本研究实习的好处。一年一度的国际研讨会创新亚洲将为学生提供额外的机会，从比较的角度审视技术与全球化之间的关系。

OISE-0530220 (Junichiro Kono, William Marsh Rice University)PIRE: U.S.-Japan Cooperative Research and Education: Ultrafast and Nonlinear Optics in 6.1-Angstrom SemiconductorsKono This Partnership for International Research and Education, led by Junichiro Kono of Rice University, investigates the ultrafast and nonlinear optical properties of quantum structures based on the 6.1-angstrom (A) III-V semiconductors (InAs, GaSb, AlSb). These semiconductors are nearly lattice-matched (with lattice constant ~ 6.1 A) and can be epitaxially grown to form heterostructures. Though they possess promising properties for application in next-generation devices, there has been little exploration of their optical properties, especially in the time domain and at high laser intensities. Various optical spectroscopic methods will be used to study charge and spin dynamics. Such studies are not only expected to increase understanding of the states and dynamics of interacting electrons but also to provide new insight into which structures are optimum for specific applications. The project establishes a long-term partnership between Rice University, University of Florida and Texas A&M University in the U.S. and Osaka Institute of Technology and Tokyo Institute of Technology in Japan. The international partnership focuses on the complementary research strengths of each side, with Japanese collaborators providing unique materials growth and processing capabilities. The project also involves a tiered program of education activities targeting students at different stages of their academic careers to attract young people to the emerging areas of electrical engineering and the physical sciences, especially nanotechnology. The cornerstone of the education activities will be a ten-week study and research internship program in Japan for graduate and undergraduate students from U.S. universities. The annual symposium INNOVATE US-Nanotechnology will reinforce the benefits of the Japan research internships for students on returning to the U.S. The annual international symposium INNOVATE Asia will provide an additional opportunity for students to examine the relationship between technology and globalization in a comparative perspective.
