项目摘要

NON-TECHNICAL DESCRIPTION: This project focuses on the development of new artificial layered materials that advance the fundamental understanding of nanoscience at the atomic level. These materials have applications in next generation devices (spintronic and orbitronic) which have been predicted to display significant improvements in device speed and energy efficiency over conventional electronic devices. The key lies in harnessing the unexpected physical phenomena that result from the changes in structure and chemistry which occur over nanometer scales at surfaces and interfaces of perovskite oxides. Outreach activities include support for the UC Davis Science, Technology, Engineering, and Mathematics Transfer Day which targets educationally disadvantaged and underrepresented groups from Mathematics Engineering Science Achievement programs in Northern California.TECHNICAL DETAILS: The goal of this project is to develop a fundamental understanding of interfacial phenomena such as exchange coupling interactions at interfaces between ferromagnetic and antiferromagnetic layers. Perovskite oxides are ideal candidate materials for these studies due to their wide range of functional properties that result from the strong coupling between the charge, spin, orbital, and lattice degrees of freedom. In addition, they possess a large number of cations and growth parameters that can be used to manipulate their properties. The approach of this work utilizes laser-assisted growth to control interfacial properties with atomic layer precision in combination with state-of-the-art techniques for characterizing their structural, chemical, and functional properties over multiple length scales. In addition, geometric confinement effects as these materials are patterned down to nanoscale dimensions are being investigated. These results are enabling the development of predictive models of the emergent interfacial properties at dimensions relevant for device applications The participating graduate and undergraduate students are gaining hands-on training in disciplines that lie at the intersection between the traditional fields of Materials Science and Engineering, Physics, and Electrical Engineering through the introduction to state-of-the-art synthesis, sophisticated characterization techniques, and theoretical calculations.
非技术描述:该项目专注于开发新的人工分层材料,以促进在原子水平上对纳米科学的基本理解。这些材料在下一代设备(自旋电子学和轨道电子学)中有应用,据预测,与传统电子设备相比,这些设备在设备速度和能源效率方面将有显著改进。关键在于利用钙钛矿氧化物表面和界面上发生的纳米级结构和化学变化所产生的意想不到的物理现象。外展活动包括支持加州大学戴维斯分校科学、技术、工程和数学迁移日,该活动针对北加州数学工程科学成就计划的教育弱势群体和代表不足的群体。技术细节:该项目的目标是发展对界面现象的基本了解,例如铁磁层和反铁磁层之间的界面交换耦合相互作用。钙钛矿氧化物由于其广泛的功能性质而成为这些研究的理想候选材料,这些性质是由于电荷、自旋、轨道和晶格自由度之间的强烈耦合而产生的。此外,它们还拥有大量的阳离子和生长参数,可以用来控制它们的性质。这项工作的方法利用激光辅助生长来控制界面属性,原子层精度与最先进的技术相结合,在多个长度尺度上表征其结构、化学和功能属性。此外,随着这些材料被图案化到纳米尺度,几何限制效应也在研究中。这些结果使得在与设备应用相关的维度上开发新出现的界面性质的预测模型成为可能。参与培训的研究生和本科生正在通过引入最先进的合成、复杂的表征技术和理论计算,在材料科学与工程、物理和电气工程等传统领域的交叉学科中获得实践培训。
