CAREER: Micro/Nano-Fabrication of Conjugated Polymers

9501716为了提高封装密度、效率和运行速度，科拉德对更小、更多功能的电子和光电子设备的需求继续增长。对越来越小的设备的探索现在已经到达了最后的前沿，即分子尺度。器件尺寸的进一步缩小必须发生在解决分子系综的水平上，或者更有趣的是，解决离散分子的问题。通过使用扫描探针显微镜技术和已经合成的新型聚碘共轭聚合物的分子构建块，我们提议创建明确的、坚固的和功能性的纳米结构，这将测试超小型化的极限。这种方法依赖于用单体的单分子层作为聚合物沉积的模板来修饰衬底。该研究计划将深入了解各种电子材料的集成和纳米制造方法，并将提供材料和方法，对与电子行业相关的复合系统的界面行为进行精确控制。从长远来看，有机纳米结构在微电路元件和量子波器件的设计中具有极大的灵活性。本研究要解决的关键问题包括：什么材料可以用来制造微纳结构；如何制造纳米级的特征；特征尺寸的限制是什么，这些特征的稳定性和性质是什么？我们目前参与了佐治亚理工学院和亚特兰大地区的许多项目，以增加学生对技术教育的参与，包括针对少数族裔、女性和大学预科学生的项目。通过一个科学博物馆的本科生外展计划，我们正在开发插图式的互动化学展品，以及一个充满活力的演示和研讨会计划。课程开发活动包括开发一门几乎完全基于解决问题的高级有机化学课程，引入一门聚合物化学课程，以及开发跨学科实验室实验。***

9501716 Collard Demand for smaller, more versatile electronic and opto-electronic devices continues to grow in order to increase packing density, efficiency and operational speed. The search for smaller and smaller devices has now reached the final frontier, the molecular scale. Further reduction in device size must occur at a level which addresses ensembles of molecules, or, more intriguing, discrete molecules. Through the use of scanning probe microscopic techniques and with novel molecular building blocks of pi-conjugated polymers that have already been synthesized, we propose to create defined, robust, and functional nanostructures which will test the limits of ultraminiaturization. This approach relies on the modification of substrates with monolayers of monomers that serve as templates for polymer deposition. The research program will provide insight into approaches for integration and nanofabrication of various electronic materials and will furnish materials and methods that provide precise control over the interfacial behavior of composite systems relevant to the electronics industry. %%% In the long term, organic nano-architectures promise great flexibility in the design of microcircuitry elements and quantum wave devices. The key issues to be addressed in this research include: What materials can be used to fabricate micro- and nanostructures; how can nanoscale features be produced; what are the limits of feature dimensions, and what are the stability and properties of these features? We are currently involved in a number of programs at Georgia Tech and in the Atlanta area to increase the involvement of students in technical education, including programs for minorities, women, and precollege students. Through an undergraduate outreach program to science museums we are developing illustrative interactive chemistry exhibits, and a vibrant demonstrat ion and workshop program. Curriculum development activities include development of an advanced organic chemistry course based almost entirely on problem solving, introduction of a polymer chemistry course, and development of interdisciplinary laboratory experiments. ***
