NIRT: Fabrication of Functional Architectures through the Directed Assembly of Nanoscale Building Blocks

摘要本课题是响应NSF纳米尺度科学与工程计划，NSF 03-043， NIRT类别。该计划将利用纳米光刻图案阵列来指导纳米级磁性构建块的组装到特定的体系结构中。这些订购的组件将设计用于高频，磁输运和机械设备的应用。个体和集体属性的微磁建模，以及属性测量的反馈，将允许对建筑设计进行积极的改进。随着科学家们开发出尺寸越来越小的材料，需要能够将这些微小的元素集成到具有技术意义的设备中。在这个程序中，非常小的组件（比人的头发小得多）将被组装成有序的数组，将它们放置在具有特定凹槽图案的表面上。凹槽将用于捕获特定方向的组件（例如小金属线）。然后，这些安排将对通信或磁性设备的潜在应用感兴趣，这些设备分别对蜂窝电话和计算机硬盘驱动器很重要。此外，在纳米科学暑期研究项目中，一个扩展部分将包括来自代表性不足群体的高中教师和本科生。

AbstractThis proposal was received in response to Nanoscale Science and Engineering initiative, NSF 03-043, category NIRT. This program will utilize nanolithographically-patterned arrays to direct the assembly of nanoscale magnetic building blocks into specific architectures. These ordered assemblies will be designed for applications in high frequency, magnetotransport, and mechanical devices. Micromagnetics modeling of individual and collective properties, along with feedback from property measurements, will allow for an active refinement of architectural designs. As scientists develop materials with smaller and smaller sizes, there is a need to be able to integrate these tiny elements into devices of technological significance. In this program, very small components (much smaller than a human hair) will be assembled into ordered arrays by placing them onto surfaces that have specific grooved patterns. The grooves will serve to capture the components (e.g. small metal wires) in specific orientations. These arrangements will then be of interest for potential applications in communication or magnetic devices such as those important to cellular phones and computer hard drives, respectively. Additionally, an outreach component will involve both high school teachers and undergraduates from underrepresented groups in a nanoscience summer research program.
