ORGANICS: Patterned Fabrication of Organic Conductors at the Nanoscale

这项提议的目的：这项提议的目的是开发在纳米尺度上制造图案化的导电有机结构域的一般方法。这将通过使用浸渍笔纳米光刻(DPN)在硅上制备双组分(有机施主/受主)电荷转移(CT)单分子层的图案化结构来实现。将通过扫描探针显微镜测量硅上CT单分子层的电学性质，以确定是否适用于晶体管和共振隧道二极管等电子设备应用，以及由这些设备功能构建的更复杂的电路。智能优势和更广泛的影响：利用分子组件制造逻辑和存储设备是一个具有挑战性的目标，可以使特殊用途的电子电路比现有的硅(CMOS)技术制造的电路小、快、价格低几个数量级。在纳米尺度上制造分子组件也带来了巨大的挑战，包括合成(化学)、明确的表征(物理)以及将功能行为应用于有用的设备。浸渍笔纳米光刻技术(DPN)将首次用于在电子给体的单分子层上传递纳米级的精密电子受体，以定义由分子组成的图案化导电区。如果有一天电子设备是由分子组装而成的，那么设备技术的新纪元就会诞生。虽然这种革命性的技术转变的后果今天无法准确评估，但它对制造业、国家和全球经济的影响可能是巨大的。本课程将吸引研究生和本科生参与。PI都积极参与他们机构的教育推广计划，这些计划寻求整合研究的见解和方法，并通过研究生和普通公众来告知和激励预科学生。

Objective of this Proposal: The objective of this proposal is to develop general methods for the fabrication of patterned electrically conducting organic domains at the nanoscale. This will be accomplished by using dip pen nanolithography (DPN) to prepare patterned structures of two-component (organic donor/acceptor) charge transfer (CT) monolayers on silicon. The electrical properties of CT monolayers on silicon will be measured by scanning probe microscopies to determine suitability for electronic device applications such as transistors and resonant tunneling diodes, as well as more complex circuitry built from these device functionalities.Intellectual Merit and Broader Impact: The fabrication of logic and memory devices from molecular components is a challenging goal that could enable special purpose electronic circuits that are orders of magnitude smaller, faster, and less expensive than those made by existing silicon (CMOS) technology. Fabricating molecular components at the nanometer scale also brings enormous challenges in synthesis (chemistry), characterizing unequivocally (physics), and adapting functional behavior into useful devices. Dip pen nanolithography (DPN) will be used for the first time to deliver with nanoscale precision electron acceptors over monolayers of electron donors to define patterned conducting regions made from molecules. If electronic devices are one day assembled from molecules, a new era in device technology would be born. While the consequences of such a revolutionary shift in technology cannot accurately be assessed today, the impact to manufacturing and the national and global economy could be significant. This program will engage the participation of graduate and undergraduate students. The PI's both actively participate in their institutions' educational outreach programs, which seek to integrate the insights and approaches of the research, and to inform and inspire pre-college through graduate students, as well as the general public.
