****Non Technical Abstract****This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). We are living in a fast-paced world of modern quantum technology where better understanding of the quantum states and interactions in semiconductor materials can play an important role in developing the next generation of devices. Some of these devices will likely make use of a quantum property of electrons known as ?spin.? This CAREER award funds projects to establish several optical, magneto-optical, and transport techniques to advance current understanding of quantum phenomena in semiconductor structures where the spin strongly affects the motion of the electrons. Understanding the quantum phenomena in these material systems will be an important step in the development quantum semiconductor devices, but equally important, will provide an environment to explore challenging phenomena in condensed matter physics. The research activities will involve diverse groups of undergraduate and graduate researchers in frontier projects to train the next generation of experts in semiconductor optics with ample knowledge of solid state and quantum physics. One important educational aspect of this CAREER award is collaborations with Roanoke Governor?s High School. Lectures on modern and recent topics in physics for the students who attend the high school from seven districts in the New River Valley will be provided. In addition, the students will have opportunities for short internship programs.****Technical Abstract****This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). In light of the current interest in spin-related phenomena, there has been growing activity in understanding and manipulating spin-orbit (SO) interactions in low dimensional semiconductor structures. The goal of the research supported by this CAREER award is to explore the quantum states and dynamics of interacting and confined electrons in low dimensional semiconductor structures with strong SO interactions. Several optical, magneto-optical, and transport techniques will be employed to advance our understanding of quantum phenomena in semiconductor structures such as InSb/AlInSb and InNAs/GaAs based heterostructures. A broader impact of the activities in this project is increasing our students? knowledge and skills in different aspects of modern experimental techniques and deepening their understanding of fundamental physics. One important aspect of the educational plans of this CAREER award is collaborations with Roanoke Governor?s High School. Lectures on modern and recent topics in physics for the students who attend the high school from seven districts in the New River Valley will be provided. In addition, the students will have opportunities for short internship programs.

****非技术摘要****该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。 我们生活在一个快节奏的现代量子技术的世界中，对量子状态的更好理解和半导体材料中的相互作用可以在开发下一代设备中发挥重要作用。 这些设备中的一些可能会利用称为“自旋”的电子的量子特性。 该职业奖资金为建立几种光学，磁光和运输技术的项目提供了资金，以提高对半导体结构中量子现象的当前理解，在这种半导体结构中，旋转强烈影响电子的运动。 了解这些材料系统中的量子现象将是开发量子半导体设备的重要一步，但同样重要的是，将为探索凝聚态物理学中具有挑战性现象提供一个环境。研究活动将涉及边境项目的各种本科生和研究生研究人员群体，以培训对固态和量子物理学充分了解的半导体光学专家的下一代专家。该职业奖的一个重要教育方面是与罗阿诺克州长高中的合作。将提供有关新河谷七个地区上高中的学生的现代和最新物理主题的讲座。此外，学生将有短暂的实习计划的机会。 鉴于当前对自旋相关现象的兴趣，在低维半导体结构中理解和操纵自旋轨道（SO）相互作用方面的活性增长。 该职业奖支持的研究的目的是探索在低维半导体结构中具有强大相互作用的量子状态和互动和限制电子的动态。将采用几种光学，磁光和传输技术来促进我们对诸如INSB/ALINSB和基于Innas/GAAS的异质结构等半导体结构中量子现象的理解。 该项目中活动的广泛影响正在增加我们的学生吗？现代实验技术不同方面的知识和技能，并加深了他们对基本物理学的理解。该职业奖的教育计划的一个重要方面是与罗阿诺克州长高中的合作。将提供有关新河谷七个地区上高中的学生的现代和最新物理主题的讲座。此外，学生还将有机会进行简短的实习计划。
