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

OISE-0530220（Junichiro Kono，William Marsh Rice University）PIRE：美国-日本合作研究和教育：6.1埃半导体的超快和非线性光学Kono由莱斯大学的Junichiro Kono领导的国际研究和教育合作伙伴关系，研究基于6.1埃（A）III-V半导体（InAs，GaSb，AlSb）的量子结构的超快和非线性光学特性。这些半导体几乎是晶格匹配的（晶格常数~6.1 A），可以外延生长形成异质结构。虽然它们具有在下一代器件中应用的有前途的特性，但是很少有人探索它们的光学特性，特别是在时域和高激光强度下。各种光学光谱方法将用于研究电荷和自旋动力学。这些研究不仅有望增加对相互作用电子的状态和动力学的理解，而且还将为特定应用提供最佳结构的新见解。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坂工业大学和东京工业大学之间的长期合作伙伴关系。&国际合作的重点是双方互补的研究优势，日本合作者提供独特的材料生长和加工能力。该项目还涉及针对处于不同学术生涯阶段的学生的分层教育活动计划，以吸引年轻人进入电子工程和物理科学，特别是纳米技术的新兴领域。教育活动的基石将是在日本为美国大学的研究生和本科生提供为期十周的学习和研究实习计划。年度研讨会创新美国纳米技术将加强日本研究实习的学生返回美国的好处年度国际研讨会创新亚洲将提供一个额外的机会，让学生检查技术和全球化之间的关系在比较的角度来看。

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.
