This Phase I CCI focuses on the important question of how to use molecules to replace bulk materials as components in integrated circuits (IC's). The dramatic improvements of electronic device performance have been a direct consequence of steady improvements in "top-down" methods to fabricate IC's, but feature sizes are rapidly approaching the limits of traditional lithographic methods. In addition, device improvements have not scaled with the latest generations of line-width improvements and new ways to carry out computation and data storage are being explored. Molecular electronics, which substitute nanoparticles and molecule based structures in place of bulk materials currently used in IC's, offer the potential to address these challenges. Unleashing this potential will require new fabrication methods that allow control of the location, dimension, and orientation at the molecular level. The initial focus of the Phase I Center for Nanostructured Electronic Materials is research in 2D directional growth with novel use of chemical precursors and synthetic methods, such as surface plasmon-mediated chemical deposition (SPMCD) that exploits the optical properties of nanoparticles for selective growth of material at specific locations. The non-destructive fabrication of electrical contacts (junctions) between juxtaposed molecular electronic components will be approached by electron beam induced dissociation (EBID) and electrodeposition of contact materials. The research will be extended to 3D growth techniques where specific chemical interactions, involving self-assembled monolayers and tailored chemical precursors, can be applied to induce preferential growth in the z direction. The size and proximity of the nanostructures explored in this program will enable the unprecedented utilization of quantum confinement, coulomb charging and proximal optical coupling for fabrication of potentially new nanoelectronic and nanophotonic devices. This CCI will foster close collaborations between experts in the development of new nanoscale electronic materials and specialists in the creation of prototypes with direct technological relevance. Participants at the University of Florida, University of Illinois at Urbana-Champaign and the University of Georgia will collaborate with industrial mentors from companies on the forefront of development of molecular electronics, who will provide an industrial perspective on materials requirements, device design and manufacturing. The focus of the Center for Nanostructured Electronic Materials on chemistry-based approaches to molecular electronics for applications in the microelectronics industry is a crucial component of America's competitive edge in technology. Such innovation would aid US national economic competitiveness as articulated in the American Competitiveness Initiative. Within this context, the center will educate students for interdisciplinary collaborative work by building team-based problem solving skills that reach outside the students' own disciplines. Internships, mentoring of undergraduate researchers, and interactions with industrial research personnel will be used to further broaden the students' perspectives. In order to communicate the excitement of science to the general public, the CCI will develop a series of two-minute radio spots and podcasts that will feature real world applications of chemistry and materials science research. To enable broader participation by under-represented groups, the CCI will partner with the established broadening participation programs of the three universities participating in this CCI to recruit and mentor minority and female undergraduates and Ph.D. students. The Centers for Chemical Innovation (CCI) Program supports research centers that can address major, long-term fundamental chemical research challenges that have a high probability of both producing transformative research and leading to innovation. These Centers will attract broad scientific and public interest by sharing the results of their innovative approach to this challenging question.

该阶段I CCI重点介绍了如何使用分子代替综合电路（IC）中的组件的重要问题。 电子设备性能的显着改善是制造IC的“自上而下”方法稳定改善的直接结果，但是功能尺寸迅速接近传统光刻方法的范围。 此外，正在探索最新一代的线路宽度改进和进行计算和数据存储的新方法。 分子电子产品代替了IC当前使用的散装材料，它代替了基于纳米颗粒和分子的结构，它提供了解决这些挑战的潜力。 释放这种潜力将需要新的制造方法，以控制分子水平的位置，维度和方向。 I阶段纳米结构电子材料中心的初始重点是研究2D定向生长的研究，并通过新颖的化学前体和合成方法（例如表面等离子体膜介导的化学沉积（SPMCD））利用纳米颗粒的光学特性用于选择性生长特定位置的材料。 电子束诱导的解离（EBID）和接触材料的电沉积将接近并置分子电子组件之间的电触点（连接）的非破坏性制造。 这项研究将扩展到3D生长技术，其中特定的化学相互作用（涉及自组装单层和量身定制的化学前体）可以应用于在Z方向上诱导优先生长。 该程序中探索的纳米结构的大小和接近度将使量子限制，库仑充电和近端光学耦合的前所未有的利用，用于制造潜在的新纳米电信和纳米光子设备。 该CCI将促进在新的纳米级电子材料开发方面的专家之间的密切合作，以创建具有直接技术相关性的原型专家。 佛罗里达大学，伊利诺伊大学Urbana-Champaign和佐治亚大学的参与者将与来自分子电子发展最前沿的公司的工业导师合作，他们将对材料需求，设备设计和制造业提供工业视角。 纳米结构材料中心的重点是针对微电子行业应用的基于化学的分子电子产品的方法，是美国技术竞争优势的重要组成部分。 这种创新将有助于美国竞争力倡议中所阐明的美国国家经济竞争力。在这种情况下，该中心将通过建立基于团队的问题解决技能来教育学生进行跨学科的合作工作，这些技能能够涉及学生自己的学科。实习，指导本科研究人员以及与工业研究人员的互动将用于进一步扩大学生的观点。为了向公众传达科学的兴奋，CCI将开发一系列两分钟的无线电点和播客，这些广播点和播客将以化学和材料科学研究的真实世界应用为特色。 为了使代表性不足的团体更广泛地参与，CCI将与参加该CCI的三所大学的既定扩大参与计划合作，以招募少数群体和女性本科生和博士学位。学生。 化学创新中心（CCI）计划支持可以解决重大长期基本化学研究挑战的研究中心，这些挑战具有产生变革性研究和导致创新的很高可能性。这些中心将通过分享其创新方法的结果来吸引广泛的科学和公众利益。
