9985492DessauThis is a CAREER award to a young faculty member at the University of Colorado who plans to study the electronic structure and physics of novel electronic systems, with particular emphasis on the high Tc superconductors. The project investigates the extension of angle-resolved photoemission spectroscopy (ARPES) using novel pump-probe techniques for measuring the unfilled density of states of materials near the Fermi level, complementary to standard ARPES. This technique gives the momentum-resolved electronic structure of a solid, information that can not be obtained by any other means. The data should be helpful for formulating theories of the mechanism of the superconductivity in these novel materials. Integrated with this research is an educational plan that will add to the involvement of students at all levels in coursework andresearch, enhance student communication activities, and include peer instruction. The PI will develop a special topics class in analytical techniques.%%%This CAREER award to a young faculty member at the University of Colorado supports research to explore the electronic structure and physics of highly correlated electron systems. One question that the research will attempt to address is, "What causes the superconductivity in the high temperature superconductors?" Although these materials have been studied for over ten years, the reasons they behave the way they do are still open to debate. The major experimental technique utilized will be angle-resolved photoemission spectroscopy (ARPES) which directly gives unique information about the electronic structure of a solid.Integrated with this research is an educational plan that includes all types of students: undergraduate, graduate, physics majors, and non-science majors. Alternate teaching methods including small discussion groups and peer instruction will be implemented at the undergraduate level. A special topics course in analytical techniques will be developed for graduate students. For all students an emphasis will be placed on developing problem solving and communication skills.***

9985492 Dessau这是一个职业奖给一个年轻的教员在科罗拉多大学谁计划研究电子结构和物理的新的电子系统，特别是在高温超导体的重点。 该项目研究了角度分辨光电子能谱（ARPES）的扩展，使用新的泵浦-探测技术测量费米能级附近材料的未填充态密度，作为标准ARPES的补充。 这种技术给出了固体的动量分辨电子结构，这是通过任何其他手段都无法获得的信息。 这些数据应该有助于制定这些新材料中超导性机制的理论。 与这项研究相结合的是一项教育计划，它将增加各级学生对课程和研究的参与，加强学生的交流活动，并包括同伴指导。 PI将开发一个分析技术的特殊主题课程。%这项职业奖授予科罗拉多大学的一名年轻教师，支持探索高度相关电子系统的电子结构和物理的研究。 该研究试图解决的一个问题是：“是什么导致高温超导体中的超导性？“虽然这些材料已经被研究了十多年，但它们的行为方式仍然存在争议。主要的实验技术将是角分辨光电子能谱（ARPES），它直接给出固体电子结构的独特信息。与这项研究相结合的是一个教育计划，包括所有类型的学生：本科生，研究生，物理专业和非科学专业。 替代教学方法，包括小型讨论小组和同伴指导将在本科阶段实施。 将为研究生开设分析技术专题课程。对于所有学生的重点将放在发展解决问题和沟通技巧。*
