CAREER: New Phases at the Surfaces/Interfaces of Transition-Metal Oxides

该职业项目将采用综合方法进行材料物理领域的研究和教育推广。过渡金属氧化物（TMO）表面/界面新相的发现、理解和设计是研究活动的目标。要解决的主要物理问题是表面金属-绝缘体转变的性质和降维纳米相分离的本质。主要方法是使用表征技术的独特组合来研究单晶或外延薄膜的明确表面的局部和全局结构和电子特性以及动态响应（包括声子和低能激发）。该项目的主要教育部分旨在解决大学预科和大学阶段的现代材料科学教育问题，以积极鼓励和促进大迈阿密地区（少数民族主导地区）的物理学（或一般物理科学）研究。活动包括：涉及本科生、高中生和教师的丰富活动和研究经验、材料研究研讨会系列以及跨学科高级材料科学课程的开发。该提案的目标是 1) 增加少数族裔学生的科学入学率，2) 培养新一代材料科学家，作为技术驱动型社会的未来劳动力，3) 探索 TMO 材料表面/界面的新物理现象，4) 开发适合未来应用所需功能的材料。该职业项目将采用综合方法进行材料物理领域的研究和教育推广。过渡金属氧化物（TMO）表面/界面新相的发现、理解和设计是研究活动的目标。主要方法是使用最先进技术的独特组合来研究单晶或外延薄膜的明确表面的局部和全局特性。这将影响对这些强相关电子材料的基础物理的理解以及它们的技术应用。该项目的主要教育部分旨在解决大学预科和大学阶段的现代材料科学教育问题，以积极鼓励和促进大迈阿密地区（少数民族主导地区）的物理学（或一般物理科学）研究。活动包括：涉及本科生、高中生和教师的丰富活动和研究经验、材料研究研讨会系列以及跨学科高级材料科学课程的开发。该提案的目标是 1) 增加少数族裔学生的科学入学率，2) 培养新一代材料科学家，作为技术驱动型社会的未来劳动力，3) 探索 TMO 材料表面/界面的新物理现象，4) 开发适合未来应用所需功能的材料。

This CAREER project will have an integrated approach to research and educational outreach in the area of materials physics. The discovery, understanding, and design of novel phases at the surfaces/interfaces of transitional-metal oxides (TMOs) are the objective of the research activities. The major physics issues to be addressed are the nature of surface metal-insulator transition and the essence of nanophase separation in reduced dimensionality. The main approach is to use a unique combination of characterization techniques to investigate both local and global structural and electronic properties and dynamical response (including phonons and low-energy excitations) of well-defined surfaces of single crystals or expitaxial thin films. The major educational component of this project is aimed at addressing modern materials science education at the pre-college and college levels to aggressively encourage and promote the study of physics (or physical science in general) in the greater Miami area, a minority-dominated region. Activities include: enrichment activities and research experience involving undergraduates, high school students and teachers, a materials research seminar series, and the development of an interdisciplinary advanced materials science curriculum. The goal of this proposal is 1) increase the minority-student enrollment in science, 2) educate a new breed of materials scientists as the future workforce for technology-driven society 3) explore new physical phenomena at surfaces/interfaces of TMO materials, and 4) exploit materials tailoring for desired functionalities for future applications.This CAREER project will have an integrated approach to research and educational outreach in the area of materials physics. The discovery, understanding, and design of novel phases at the surfaces/interfaces of transitional-metal oxides (TMOs) are the objective of the research activities. The main approach is to use a unique combination of state-of-the art techniques to investigate both local and global properties of well-defined surfaces of single crystals or expitaxial thin films. The impact will be on both the understanding of the fundamental physics of these strongly correlated electron materials and also their technological applications.
