Mapping molecular structure-property relationships for molecular electronics through the use of nanometer-scale, patterned, self-assembled monolayers and probe microscopy

北卡罗来纳州立大学化学系的戈尔曼教授和他的同事们正在研究用于构建分子电子器件的自组装单层体系置换光刻的基础科学。在分析和表面化学计划的支持下，这些单分子层的替换光刻中的结构-性质关系被用来开发可用于分子电子学应用的三维纳米结构的形成方法。特别是，这项工作集中在负阻器件的检查，以及单层材料中的电化学氧化还原转变在这些结构的操作中的影响。培养分子电子学和纳米技术领域的学生是正在进行的工作的一个更广泛的影响。发展用于构建分子电子器件的替换光刻基础科学是这项由分析和表面化学计划支持的研究项目的重点。戈尔曼教授正在系统地研究使用替代光刻方法形成的自组装单分子膜的结构和功能之间的联系。这些信息提供了设计和生产分子电子器件所需的基本理解。

AbstractCHE-0451120Gorman/NC StateProfessor Gorman and his coworkers in the Department of Chemistry at North Carolina State University are studying the fundamental science of replacement lithography on self-assembled monolayer systems, for the construction of molecular electronic devices. With the support of the Analytical and Surface Chemistry Program, structure-property relationships in the replacement lithography of these monolayers are used to develop approaches for the formation of three dimensional nanostructures that can be used in molecular electronics applications. In particular, the work concentrates on the examination of negative differential resistance devices, and the effect of electrochemical redox transitions in the monolayer materials in the operation of these structures. Training of students in the field of molecular electronics and nano-technology is one broader impact of the work being carried out.Developing the fundamental science of replacement lithography for the construction of molecular electronic devices is the focus of this research project supported by the Analytical and Surface Chemistry Program. Professor Gorman is systematically examining the connections between structure and function of self-assembled monolayers formed using replacement lithographic approaches. This information provides the fundamental understanding needed for the design and production of molecular electronic devices.
