项目摘要
The Major Research Instrumentation (MRI) program and the Historically Black Colleges and Universities-Undergraduate Program (HBCU-UP) together with the Office of Multidisciplinary Activities (OMA) in the Mathematical and Physical Sciences (MPS) directorate provide support for the acquisition of a cryogen-free Physical Property Measurement System DynaCool (PPMSD) instrument at Howard University. This acquisition supports Howard University researchers' participation in the National Quantum Initiative and the Materials Genome Initiative. The PPMSD provides a state-of-the-art resource to support students and researchers in cutting-edge quantum and materials science research. The PPMSD enhances the active learning experience at the undergraduate and graduate levels in science and engineering departments. Students receive training in magnetic, electrical transport, and heat capacity measurements, experimental data analysis, scientific writing, and presentation skills, which enhances their competitiveness with prospective employers in academia and industry. This, in turn, attracts the next generation of science and engineering students from underrepresented groups who can acquire the requisite skills and then go on to be leaders in their respective fields.The PPMSD provides the ability to perform variable temperature and magnetic field dependent magnetic, electrical transport, and heat capacity studies relating to quantum materials, magnetic materials, functional materials, and quantum devices. The PPMSD provides advanced research capabilities to undertake several basic and applied research projects that enhance understanding of: (1) the effects of dimensional crossover in mesoscale spin glass dynamics and the role it plays on cooperative phase transitions; (2) the relationships between magnetic and structural entropies, and the performance of magnetocaloric materials; (3) the relationships between electronic transport and magnetic properties in porphyrin molecular junctions; (4) the effects of adatom doping on magnetic, spectroscopic, and transport properties of two-dimensional materials, such as graphene; (5) magnetic and spin transport properties of single molecular magnets covalently bonded between the two ferromagnetic electrodes of a magnetic tunnel junction; and (6) the study of electrical and magnetic properties of recovered high-pressure phases of novel carbon-based clathrate materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
主要研究仪器(MRI)计划和历史上的黑人学院和大学本科生计划(HBCU-UP)以及数学和物理科学(MPS)董事会的多学科活动办公室(OMA)为霍华德大学的无冷冻剂物理特性测量系统DynaCool(PPMSD)仪器的收购提供支持。此次收购支持霍华德大学的研究人员参与国家量子计划和材料基因组计划。PPMSD提供最先进的资源,以支持学生和研究人员进行尖端的量子和材料科学研究。PPMSD增强了科学和工程部门本科和研究生阶段的积极学习体验。学生接受磁,电输运和热容测量,实验数据分析,科学写作和演讲技巧的培训,这提高了他们与学术界和工业界未来雇主的竞争力。这反过来又吸引了下一代科学和工程专业的学生,他们可以获得必要的技能,然后成为各自领域的领导者。PPMSD提供了进行与量子材料、磁性材料、功能材料和量子器件相关的变温和磁场相关的磁、电输运和热容研究的能力。PPMSD提供先进的研究能力,开展几项基础和应用研究项目,以提高对以下问题的理解:(1)中尺度自旋玻璃动力学中的维度交叉效应及其在合作相变中的作用;(2)磁熵和结构熵之间的关系,以及磁热材料的性能;(3)卟啉分子结中电子输运与磁性的关系:(4)吸附原子掺杂对二维材料(如石墨烯)磁性、光谱和输运性质的影响;(5)磁隧道结的两个铁磁电极之间共价键合的单分子磁体的磁性和自旋输运性质;(6)对回收的新型碳纳米管高压相的电磁性能进行了研究。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
