This Nanoscale Exploratory Research (NER) proposal was submitted in response to the solicitation "Nanoscale Science and Engineering" (NSF 02-148). The project addresses synthesis and processing of cluster based hybrid molecular-electronic architectures to overcome fundamental limits to miniaturization of solid state semiconductor mass-produced circuitry. Emphasis is on control of precise composition and the spatial arrangement of clusters. Part of the motivation for the project is that it may be possible to arrange groups of clusters so that they perform the basic functions of electronic circuits, with the presence or absence of single electrons representing bits of information. A cluster-based single-electronics technology could provide a means to overcome the technical and fundamental barriers that are expected to limit further miniaturization of current types of electronic circuit, but also set the stage for the implementation of revolutionary electronic circuit designs based on the principles of single-electronics. Preliminary studies have shown that even networks with relatively simple single-electron synapses could be sufficiently complex to reproduce some of the characteristic capabilities of the human brain. Thus extremely powerful signal processing technologies may become available in the foreseeable future. In this exploratory project molecular frameworks of sufficient size to enclose clusters will be synthesized. Initially, the frameworks will be modified by means of appended side chains to fulfill two tasks: hold clusters with diameters of up to 2 nm and mediate the attachment of "caged clusters" to solid surfaces. The electron transport properties of these caged clusters will then be studied. In subsequent work, the frameworks will be interconnected to form precisely defined cluster arrays that function as single-electron devices. Additionally, they will be interfaced with nanofabricated electronic circuits to demonstrate the feasibility of novel computing architectures based on principles of single-electronics. The proposed research is a collaborative effort involving researchers from two Departments (Chemistry; Physics and Astronomy). %%% The project addresses basic exploratory research issues in a topical area of materials science and chemistry with high technological relevance; it is considered a high risk/high pay-off activity. The project encompasses the NSE research and education theme of Nanoscale Structures, Novel Phenomena, and Quantum Control. An important feature of the program is the integration of research and education through the training of students in a fundamentally and technologically significant area. The scope of the project is interdisciplinary, spanning atom-by-atom construction and physical characterization of nanostructures to the integration of such structures with existing technology. This interdisciplinary research setting is expected to attract students to nanoscience and provide a unique training ground for young scientists at all stages of their education and training. The research results will be published in scientific journals, and also used to attract local undergraduate and high school students into research activities. The project is jointly supported by the MPS/DMR/EM and the MPS/CHE Special Projects and IBO programs.

本纳米尺度探索性研究（NER）提案是响应“纳米尺度科学与工程”（NSF 02-148）招标而提交的。该项目致力于基于簇的混合分子电子结构的合成和处理，以克服固态半导体批量生产电路小型化的基本限制。重点是控制集群的精确组成和空间安排。这个项目的部分动机是，有可能安排成组的簇，这样它们就可以执行电子电路的基本功能，单个电子的存在或不存在代表信息位。基于集群的单电子技术可以提供一种方法来克服技术和基本障碍，这些障碍预计会限制当前类型的电子电路进一步小型化，但也为基于单电子原理的革命性电子电路设计的实施奠定了基础。初步研究表明，即使是具有相对简单的单电子突触的网络，也可能足够复杂，足以重现人类大脑的一些特征能力。因此，在可预见的未来，强大的信号处理技术可能会成为可能。在这个探索性项目中，将合成足够大小的分子框架来包裹簇。最初，框架将通过附加侧链的方式进行修改，以完成两个任务：保持直径高达2纳米的簇，并调解“笼状簇”对固体表面的附着。然后将研究这些笼状团簇的电子输运性质。在随后的工作中，这些框架将相互连接，形成精确定义的簇阵列，作为单电子设备。此外，它们将与纳米制造的电子电路相连接，以展示基于单电子原理的新型计算架构的可行性。这项拟议的研究是两个系（化学系、物理系和天文学）的研究人员共同努力的结果。该项目在材料科学和化学的一个具有高技术相关性的主题领域进行基础探索性研究；它被认为是高风险/高回报的活动。该项目涵盖了NSE的研究和教育主题：纳米结构、新现象和量子控制。该计划的一个重要特点是通过培养学生在一个基础和技术上重要的领域的研究和教育的整合。该项目的范围是跨学科的，涵盖了原子对原子的构建和纳米结构的物理表征，以及这些结构与现有技术的集成。这种跨学科的研究环境有望吸引学生研究纳米科学，并为处于教育和培训各个阶段的年轻科学家提供一个独特的培训场所。研究成果将发表在科学期刊上，并用于吸引当地的本科生和高中生参与研究活动。该项目由MPS/DMR/EM和MPS/CHE特别项目和国际文凭组织方案联合支持。
