CAREER: Crystal Growth and Scattering Studies of Transition Metal Oxides

这是一个职业生涯奖，授予斯坦福大学的一位年轻教员，他将建立一个研究项目，研究复杂的“相关电子”过渡金属氧化物的性质。该项目将发展培养高质量过渡金属氧化物单晶的能力。晶体将使用x射线散射和中子散射在两个国家设施（斯坦福同步辐射实验室和国家标准与技术研究所分别）进行表征。该项目将增加我们对高温超导体、量子磁性和强相关金属的理解，以及这些材料所表现出的所有行为。这些课题处于凝聚态物理研究的前沿。与这项研究相结合的是一项教育计划，该计划将在本科和高中阶段接触到自然科学领域代表性不足的群体。来自困难社区的高中生将有机会进行一些令人兴奋的暑期研究。将为本科高年级和研究生一年级的学生开设一门关于散射的课程。这是一个终身成就奖，授予斯坦福大学的一位年轻教员，他将建立一个研究项目，研究由过渡金属和氧的平面或链构成的奇异晶体。它们以独特的方式表现，可能会揭示对自然的全新认识。例如，通过将它们置于磁场中或施加压力，它们可以从不良导体变为良导体。铜和氧的平面也是高温超导体的关键成分——当冷却到液氮的温度时，这种材料可以无电阻地导电。该项目包括将这些材料培养成晶体，然后在几个国家实验室用x射线和中子束轰击它们。对这些奇异晶体的研究处于凝聚态物理的前沿。与这项研究相结合的是一个创新的高中外展项目，涉及来自东帕洛阿尔托的学生，这是美国陷入困境的社区之一。该计划将提供令人兴奋的夏季研究机会，涉及附近的国家实验室，斯坦福同步辐射实验室（SSRL）。此外，本研究项目将特别努力让来自自然科学领域代表性不足群体的本科生参与进来

This is a CAREER award to a young faculty member at Stanford University who will setup a research program to grow and study the properties of complex "correlated-electron" transition metal oxides. The project will develop the ability to grow high quality single crystals of transition metal oxides. The crystals will be characterized using X-ray scattering and neutron scattering at two national facilities (Stanford Synchrotron Radiation Laboratory and the National Institute of Standards and Technology respectively). The project will increase our understanding of high temperature superconductors, quantum magnetism, and strongly correlated metals, all behaviors exhibited by these materials. These topics are at the forefront of condensed matter physics research.Integrated with this research is an educational plan that will reach out to under-represented groups in the natural sciences, both at the undergraduate and high school level. High school students from a troubled community will be provided the opportunity to perform some exciting summer research. A course in scattering will be developed for students at the upper-undergraduate and first year graduate level.%%%This is a CAREER award to a young faculty member at Stanford University who will set up a research program to study exotic crystals made from planes or chains of transition metals and oxygen. They behave in unique ways that may reveal fundamentally new insights into nature. For example, they can be changed from poor conductors of electricity to good conductors by placing them in a magnetic field or by applying pressure. Planes of copper and oxygen are also critical ingredients in high-temperature superconductors - materials that can carry electricity without resistance when cooled to the temperature of liquid nitrogen. The project involves growing these materials as crystals, and then bombarding them with beams of X-rays and neutrons at several national laboratories. The study of these exotic crystals is at the frontier of condensed matter physics.Integrated with this research is an innovative high school outreach program involving students from East Palo Alto, one of the nation's troubled communities. This program will provide exciting summer research opportunities involving a nearby national laboratory, the Stanford Synchrotron Radiation Laboratory (SSRL). In addition, a special effort will be made to involve undergraduate students from groups that are under-represented in the natural sciences in this research project.***
