Integrated Molecular Layer Deposition and Atomic Layer Deposition of Organic and Inorganic Thin Films

Gregory Parsons研究所：北卡罗来纳州立大学提案编号：0626256标题：有机和无机薄膜的集成分子层沉积和原子层沉积项目摘要许多新的电子系统，包括显示器、固态光源、光伏和其他能量转换设备都使用有机薄膜，其中有机材料与更传统的无机电子材料进行化学耦合。无机/有机界面的性质对控制器件的功能和性能特别重要，然而，对于形成良好控制的有机/无机界面所需的化学过程，没有重要的基础知识。因此，该项目将解决与气源沉积以及有机和无机薄膜材料的原子尺度组合相关的基本物理和化学挑战。这项工作将扩展分子气相沉积的新兴领域，包括研究共价键合的有机单层和多层聚合物薄膜，以及将分子气相沉积与原子层沉积相结合，以实现有机/无机集成异质结构。一个关键的活动将是确定在有机表面沉积金属覆盖层的反应方案，该反应方案对有机物造成最小的损害，同时获得由电子、物理和化学表征探针确定的良好的界面结构。主要的智力优势包括：a)更好地了解有机薄膜和有机/无机界面处理，包括更好地洞察沉积中的传输和反应机制；b)在纳米级结构制造中改进对横向和垂直成键结构的控制；c)在地层化学和高性能器件功能之间建立明确的关系；以及d)扩展基于分子的工艺所需的知识。这项工作通过影响和定义未来有机和混合有机/无机器件制造和制造的方法，具有广泛影响的潜力。它还将对教育产生影响，参与课程的学生将在有机材料和薄膜加工方面获得广泛的跨学科经验。本科生和研究生将通过实验项目和PIS年度课程电子材料化学加工向学生介绍与该项目相关的新结果和见解。PIS与对有机材料和有机电子设备感兴趣的公司的互动将有助于将这些结果迅速传播给潜在的工业用户。国际学生联合会在电子材料和加工领域成功地招募了少数族裔和女性学生，预计这项努力的资金将有助于进一步将代表性不足的群体引入这一令人兴奋的新兴领域。强调电子材料加工，包括材料的表面化学、加工和电气评价方面，将为学生在工业或学术上做出独特的贡献做好准备。

ABSTRACTPI: Gregory Parsons Institution: North Carolina State UniversityProposal Number: 0626256Title: Integrated Molecular Layer Deposition and Atomic Layer Deposition of Organic and Inorganic Thin FilmsProject SummaryMany new electronic systems, including displays, solid-state light sources, photovoltaic and other energy conversion devices make use of organic thin films, where the organic materials are chemically coupled to more traditional inorganic electronic materials. The nature of the inorganic/organic interface is particularly important in controlling device function and performance, yet there is not a significant base of fundamental knowledge regarding chemical processes needed to form well-controlled organic/inorganic interfaces. This project, therefore, will address fundamental physical and chemical challenges associated with vapor-source deposition and atomic-scale combination of organic and inorganic thin film materials. The work will expand the emerging field of molecular vapor deposition to include study of covalently bound organic monolayer and multilayer polymeric films, as well as combining molecular vapor deposition with atomic layer deposition to achieve integrated organic/inorganic heterostructures. A key activity will be to identify reaction schemes for depositing metal overlayers onto organic surfaces that impart minimal damage to the organic, while achieving good interface structure as determined by electronic, physical, and chemical characterization probes. The key intellectual merit includes: a) improved understanding of organic thin film and organic/inorganic interface processing, including better insight into transport and reaction mechanisms in deposition; b) improved control over lateral and vertical bonding structure in nanometer-scale structure fabrication; c) establishment of well defined relations between formation chemistry and high-performance device function; and d) expanding the knowledge needed to scale-up molecule-based processes.Broad Impact This work has the potential for broad impact by influencing and defining methodology for future organic and hybrid organic/inorganic device fabrication and manufacturing. It will also have educational impact, the students involved will gain a broad interdisciplinary experience in organic materials and thin film processing. Undergraduate and graduate students will be introduced to new results and insights related to this project through lab projects, and through the PIs annual course Chemical Processing of Electronic Materials. The PIs interactions with companies interested in organic materials and organic electronic devices will help to quickly disseminate these results to potential industrial users. The PI has been successful at recruiting minority and female students into the area of electronic materials and processing, and it is anticipated that funding from this effort will help to further introduce under-represented groups to this exciting emerging field. The emphasis on electronic materials processing, including aspects of surface chemistry, processing, and electrical evaluation of materials, will prepare the students to make unique contributions in industry or academics.
