项目摘要

Non-technical abstract:Quantum materials are an emergent field integrating many science disciplines to develop next generation electronic and energy technology. A well-known example of quantum materials is the high temperature superconductor, which brings promise of electricity transfer without energy loss. The acquisition of the cryogen-free Physical Properties Measurement System (PPMS) enables researchers at the University of Michigan to measure the properties of next-generation materials. The fundamental understanding gained from the study of quantum materials lays the foundation for future electronics, including high-density hard drives, quantum computers, and semiconductor panels that generate electricity using solar energy or waste heat from your car engine. The PPMS provides excellent avenues for training graduate and undergraduate students. The students perform research using state-of-the-art equipment and receive education and training in an interdisciplinary environment. PPMS allows undergraduate and high school students, doing research with the investigators, and those taking upper level physics laboratory courses, to easily and safely perform experiments at cryogenic temperatures. The investigators leverage existing REU and bridge-to-PhD programs to bring in students from underrepresented groups to participate in projects on quantum electronic materials, which enhance the diversity of the future US STEM workforce. Technical Abstract:The acquisition of a cryogen-free Physical Properties Measurement System (PPMS) with a 14 Tesla magnet enables studies of novel quantum materials at the University of Michigan in order to answer the following important problems. (1). What fundamentally new physics and novel functionalities can be achieved in 2D electronic systems by strong electronic correlations, interface engineering, and edge valley polarization? (2). Why are the most well known 3D Dirac electronic systems good thermoelectric materials? (3). What are the key parameters determining the optoelectronic properties of dilute semiconductor alloys? (4). How are spins coupled to the electronic degrees of freedom in conventional and novel semiconductors? Aiming to answer these fundamental questions, the scope of research includes: (1) Emergent novel two-dimensional electronic systems, (2) Enhanced Thermoelectric materials in 3D Dirac electronic systems, (3) Physical properties of Semiconductor Alloys, and (4) Manipulating spin and magnetic properties in semiconductors. The methods and approaches of the research explore a broad range of physical properties including resistivity, Hall effect, magnetization, heat capacity, AC susceptibility, thermal conductivity, and thermopower. The studies enable understanding of physical mechanisms, and lay the foundation for important and novel applications of quantum materials.
非技术摘要:量子材料是一个新兴的领域,融合了许多科学学科,以发展下一代电子和能源技术。量子材料的一个众所周知的例子是高温超导体,它带来了无能量损失的电力传输的希望。无冷冻剂物理性能测量系统(PPMS)的收购使密歇根大学的研究人员能够测量下一代材料的性能。从量子材料研究中获得的基本理解为未来的电子产品奠定了基础,包括高密度硬盘驱动器,量子计算机和半导体面板,这些面板可以利用太阳能或汽车发动机的废热发电。PPMS为培养研究生和本科生提供了很好的途径。学生使用最先进的设备进行研究,并在跨学科的环境中接受教育和培训。PPMS允许本科生和高中生与研究人员一起进行研究,以及那些参加高级物理实验室课程的学生,在低温下轻松安全地进行实验。研究人员利用现有的REU和桥梁博士课程,将来自代表性不足的群体的学生引入量子电子材料项目,这将增强未来美国STEM劳动力的多样性。 技术摘要:收购一个无致冷剂的物理特性测量系统(PPMS)与14特斯拉磁铁使新的量子材料的研究在密歇根大学,以回答以下重要问题。(一).通过强电子相关、界面工程和边谷极化,在2D电子系统中可以实现哪些全新的物理和新功能? (二)、为什么最著名的3D狄拉克电子系统是良好的热电材料?(三)、决定稀半导体合金光电性能的关键参数是什么?(四)、在传统和新型半导体中,自旋是如何与电子自由度耦合的?为了回答这些基本问题,研究范围包括:(1)新兴的二维电子系统,(2)3D狄拉克电子系统中的增强热电材料,(3)半导体合金的物理性质,以及(4)操纵半导体中的自旋和磁性。研究的方法和途径探索了广泛的物理性质,包括电阻率,霍尔效应,磁化,热容,交流磁化率,热导率和热功率。这些研究使人们能够理解物理机制,并为量子材料的重要和新颖应用奠定基础。
