CAREER: Research and Education in Materials Physics

9703419徐的职业生涯计划旨在加强北卡罗来纳大学教堂山分校的材料物理研究和教育。研究部分探索通过分子束外延技术生长的金属薄膜和多层膜的原子尺度合成和表征。它集中于三个主要目标：(1)阐明外延形核和生长过程中的扩散过程，并开发制备定制外延结构和形貌的技术；(2)了解金属多层膜中引起振荡磁耦合和巨磁电阻效应的自旋相关散射的本质；(3)通过探索单分子层和亚单层体系来揭示低维半分子膜。教育部分旨在对社会的知识氛围产生积极影响。它采取了双管齐下的战略。首先，它侧重于通过将传统的授课报告转变为参与性的、基于发现的课程来提高课堂教学效率。其次，为教堂山-达勒姆地区的高中教师和学生开发了人工结构纳米材料的研究和教育机会。面向当地社区的外展活动包括导师计划、实验室之旅和日记俱乐部。该职业生涯计划旨在加强北卡罗来纳大学教堂山分校的材料物理研究和教育。研究部分集中于探索合成金属纳米结构的新的电磁性能。它试图阐明人为限制对材料性能的作用，并增强我们生产定制电子和磁性结构的能力。它是通过使用最先进的技术，包括分子束外延和扫描探针显微镜，对原子尺度、材料合成和材料性质进行系统研究而进行的。教育部分旨在对社会的知识氛围产生积极影响。它采取了双管齐下的战略。首先，它侧重于通过将传统的授课报告转变为参与性的、基于发现的课程来提高课堂教学效率。其次，为教堂山-达勒姆地区的高中教师和学生开发了人工结构纳米材料的研究和教育机会。面向当地社区的外展活动包括导师计划、实验室之旅和日记俱乐部。***

9703419 Tsui The CAREER plan seeks to enhance both research and education in materials physics at the University of North Carolina at Chapel Hill. The research component explores atomic scale synthesis and characterization of metallic thin films and multilayers grown by molecular beam epitaxy techniques. It focuses on three main objectives: (1) to elucidate diffusion processes during epitaxial nucleation and growth, and to develop techniques for producing tailored epitaxial structures and morphologies, (2) to understand the nature of spin-dependent scattering responsible for the oscillatory magnetic coupling and giant magnetoresistance effects in metallic multilayers, and (3) to shed light on low- dimensional penomensa by exploring monolayer and submonolayer systems. The education component seeks to make positive impact on the intellectual climate of the community. It employs a two pronged strategy. First, it focuses on improving teaching effectiveness in the classroom by transforming traditional lecture presentations into participatory, discovery-based courses. Second, research and education opportunities in artificially structured nano- materials are developed for high school teachers and students in the Chapel Hill-Durham area. Outreach activities toward the local community include mentor programs, lab tours, and journal clubs. %%% The CAREER plan seeks to enhance both research and education in materials physics at the University of North Carolina at Chapel Hill. The research component focuses on exploring novel electrical and magnetic properties of synthetic metallic nano-structures. It seeks to elucidate the role of artificial constraints on material properties, and to enhance our ability to produce tailored electronic and magnetic sturctures. It is pursued by systematic studies of atomic scale materials synthesis and ma terials properties using state-of-th-art techniques including molecular beam epitaxy and scanning probe microscopy.
