A Combined Chemical and Microscopic Approach to Nanometer Scale Materials

这项研究计划资助项目涉及材料化学的广泛领域和纳米结构的子领域。在这项为期18个月的标准拨款期间，刘教授和她在韦恩州立大学的学生将进行初步实验，以确定纳米材料制造和表征研究计划的可行性。他们的战略方法包括制备各种纳米粒子结构和图案，包括点、线和各种形状的二维岛，然后使用力显微镜，特别是扫描隧道显微镜(STM)和原子力显微镜(AFM)来表征这些结构。纳米结构的合成将基于传统的自组装和朗缪尔-布洛杰特技术来制备模板，以及使用力显微镜的探针尖端直接电合成纳米结构。制备纳米材料并控制这些颗粒的大小和结构的能力具有巨大的基础和技术重要性。这项研究计划资助项目将导致一项对量子物理和化学具有重要性质的纳米级材料的制备和表征、新型亚微米电子器件和新型光电子材料的研究计划。

This Research Planning Grant project is in the broad area of materials chemistry and in the subfield of nanostructures. During the tenure of this eighteen-month standard grant, Professor Liu and her students at Wayne State University will conduct preliminary experiments designed to establish the feasibility of a research program in the fabrication and characterization of nanoscale materials. Their strategic approach involves the preparation of a variety of nanoparticle structures and patterns including dots, line, and two-dimensional islands with various shapes, followed by the characterization of these structures using force microscopy, particularly scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Nanostructure synthesis will be based on both traditional self-assembly and Langmuir-Blodgett techniques to prepare templates as well as the direct electrosynthesis of nanostructures using the probe tips of the force microscopes. The ability to prepare nanometer-sized materials and to control the size and structures of these particles is of immense fundamental and technological importance. This Research Planning Grant project will lead to a research program in the fabrication and characterization of nanoscale materials with `size tunable` properties of importance to quantum physics and chemistry, new sub- micron electronic devices, and novel optoelectronic materials.
