TechnicalThe theme of this project is to understand and manipulate spins and magnetismin self-assembled nanoparticle arrays with potential for spintronic and high frequency applications. Theresearch approach includes material synthesis, self-assembly, property characterization, device fabrication, and theoretical modeling to address fundamental challenges impeding progressin nanomagnetism and spintronics. Research efforts are grouped into three topics: 1) development ofnanoscale building blocks based on solution phase synthesis, with emphasis on half-metallicnanoparticles, diluted magnetic semiconductor (DMS) quantum dots (QDs) and multicomponent hybridnanoparticles; 2) fabrication and characterization of ordered nanoparticle arrays with tailored propertiesand interactions, created by the integration of self-assembly and microfabrication techniques; 3)development of functional materials and devices having potential for spintronic and high frequency applications. Non-TechnicalBroader Impact: The proposed work contains a strong educational component with a goal ofcultivating researchers with multidisciplinary skills and integrating the PI's research expertise into educational activities. These research activities lie at the intersection of physics, chemistry and engineering, involving material synthesis, device fabrication, and structural and physical property characterizations. This combination offers interdisciplinary and multi-skill training to students and postdocs. Through collaboration with IBM researchers, selected graduate and undergraduate students will be offered industrial internships. This exposure will broaden their horizons and prepare them forcareers in either academic or industrial settings. The PI expects to increase participation of women and minority students in his research program via targeted recruiting, in the form of providing research experience for undergraduates, assistantships and internships. Undergraduate students will be recruited to develop a magnetotransport measurement system, which will be used for the Department's Advanced Lab course as well as a unique tool for spin polarized transport studies. Systematic approaches will be employed to stimulate abstract thinking and logical reasoning in the teaching of undergraduate introductory physics. Research results and current and future technology trends will bepresented to a broader audience including K-12 science teachers and students, targeting high needs of inner city and Native American schools in the Buffalo area, through developing hands-on material science tools and resources.

技术该项目的主题是理解和操纵自组装纳米颗粒阵列中的自旋和磁性，具有自旋电子和高频应用的潜力。研究方法包括材料合成、自组装、性能表征、器件制造和理论建模，以解决阻碍纳米磁性和自旋电子学进步的基本挑战。研究工作分为三个主题：1）基于溶液相合成的纳米级构建块的开发，重点是半金属纳米粒子、稀磁半导体（DMS）量子点（QD）和多组分混合纳米粒子； 2）通过自组装和微加工技术的集成创建具有定制特性和相互作用的有序纳米粒子阵列的制造和表征； 3）开发具有自旋电子和高频应用潜力的功能材料和器件。非技术更广泛的影响：拟议的工作包含强大的教育成分，其目标是培养具有多学科技能的研究人员并将 PI 的研究专业知识融入教育活动中。这些研究活动处于物理、化学和工程学的交叉点，涉及材料合成、器件制造以及结构和物理性能表征。这种组合为学生和博士后提供跨学科和多技能培训。通过与 IBM 研究人员合作，选定的研究生和本科生将获得工业实习机会。这种接触将拓宽他们的视野，并为他们在学术或工业环境中的职业生涯做好准备。 PI 希望通过有针对性的招聘，为本科生提供研究经验、助学金和实习机会，增加女性和少数族裔学生对其研究项目的参与。将招募本科生开发磁输运测量系统，该系统将用于该系的高级实验室课程以及自旋极化输运研究的独特工具。在本科物理入门教学中，将采用系统的方法来激发抽象思维和逻辑推理。研究成果以及当前和未来的技术趋势将通过开发实用的材料科学工具和资源，向包括 K-12 科学教师和学生在内的更广泛受众展示，以满足布法罗地区内城区和美国原住民学校的高需求。
