This research will tackle two critical issues in future materials for advanced molecule-based information processing: 1) how to assemble and attach single molecules to electronic contacts; and 2) how to create electronic gain (the fundamental operating principle of a transistor) at the molecular level. To do this, however, this project will address three major unsolved challenges: (1) Synthesis of new molecules with functionality that allows them to act as nonlinear electronic elements and to chemically attach to silicon-based contact structures (2) Bridging the molecular (created via bottom-up fabrication) with the lithographic (created via top-down fabrication) length scales for device construction and (3) definition of new lithographic approaches that accommodate molecular installation during processing. The approach we propose addresses these issues and, in addition is designed to demonstrate the important concept of Gain at the molecular level as the result of a state change within the molecular architecture rather than as the response of a molecule to a change in bias of an underlying (macroscopic) gate electrode.The advancement of the field of molecular electronics also is fundamentally changing how the next generation of technically saavy students is educated. Under this work, we propose several activities. Graduate students will do Ph. D. degrees that involve both traditional science, engineering and technology development aspects and emphasize state-of-the-art research approaches. In addition, we describe the expansion of existing, interdisciplinary courses suited to developing critical understanding of the field of nanotechnology and an outreach program for women and minorities to expand the diversity of participation in this new, interdisciplinary paradigm.%%%Miniaturizing electronic devices to the molecular scale is the next major step in the electronics revolution. The results of this project will help ensure that better techniques for information processing will be available to keep our economy growing stronger with smaller, faster, lighter electronics. While this type of research will ultimately be performed by corporate research and development, today there are fundamental, unsolved issues that must be addressed before such entities can assume the risk of such research. These issues, if addressed using federal funds to universities will make possible the next phase of electronics development, particularly in the United States.

这项研究将解决未来先进分子信息处理材料中的两个关键问题：1)如何组装单个分子并将其连接到电子触点上；2)如何在分子水平上产生电子增益(晶体管的基本工作原理)。然而，要做到这一点，该项目将解决三个尚未解决的主要挑战：(1)合成具有功能的新分子，使其能够充当非线性电子元件并以化学方式附着到基于硅的接触结构上；(2)将分子(通过自下而上的制造)与光刻(通过自上而下的制造产生)之间的桥梁连接起来，以构建器件；(3)定义新的光刻方法，以适应加工过程中的分子安装。我们提出的方法解决了这些问题，此外，我们的设计是为了在分子水平上展示作为分子结构内状态变化的结果的重要的增益概念，而不是作为分子对潜在(宏观)门电极的偏压变化的响应。分子电子学领域的进步也从根本上改变了下一代技术精明的学生的教育方式。在这项工作下，我们提出了几项活动。研究生将攻读涉及传统科学、工程和技术发展方面的博士学位，并强调最先进的研究方法。此外，我们还描述了现有跨学科课程的扩展，这些课程适合于发展对纳米技术领域的批判性理解，并为妇女和少数民族提供了一个外联计划，以扩大参与这一新的跨学科范式的多样性。%将电子设备微型化到分子规模是电子革命的下一个重要步骤。该项目的成果将有助于确保使用更好的信息处理技术，通过更小、更快、更轻的电子产品来保持我们的经济增长强劲。虽然这种类型的研究最终将由公司研发进行，但今天在这些实体承担此类研究的风险之前，必须解决一些基本的、尚未解决的问题。如果使用联邦资金向大学解决这些问题，将使电子产品开发的下一阶段成为可能，特别是在美国。分子电子学领域的进步也从根本上改变了下一代技术精明的学生的教育方式。在这项工作下，我们提出了几项活动。研究生将攻读涉及传统科学、工程和技术发展方面的博士学位，并强调最先进的研究方法。此外，我们描述了适合发展对纳米技术领域的批判性理解的现有跨学科课程的扩展，以及针对妇女和少数民族的外展计划，以扩大参与这一新的跨学科范式的多样性。
