High-Conductivity Binary Organic Single Crystals for Electronic Applications

技术：本研究项目的主要目标是生长由有机或无机施主和受主形成的二元化合物的单晶，探索它们的物理性质，并确定最有希望在电子学和光电子学方面潜在应用的候选材料。该项目汇集了一个来自几个校区的统一的科学家团队，他们在材料生长、材料表征、器件行为和有机半导体理论方面拥有丰富的知识和经验。该团队将集中精力研究由两个不同的有机分子组成的有机二元电荷转移化合物，其中一个分子充当供体，另一个分子充当接受者。从单组分材料的研究过渡到二元和多组分材料的研究，提供了发现意想不到的材料性质和新现象的前景，因为施主和受主分子之间的分子间相互作用(电子转移起关键作用)允许新的功能。非技术性：该项目解决了材料科学的一个热门领域的基础研究问题。新的二元有机化合物的研究有可能极大地推动有机半导体领域的发展，因为它开辟了一系列单分子固体中没有的功能，并为电子学和光电子学创造了新的应用。参与这个项目的研究生将在一系列物理表征技术、器件制造和表征、量子化学计算方法和晶体生长方面获得广泛的经验。本科生将体验令人兴奋的合作和跨学科的研究主题，以及一个刺激的培训环境。研究成果将被整合到本科生和研究生级别的合作绩效指标教授的课程中，包括关于有机电子材料和器件的专题课程。它们还将用于由当地科学博物馆赞助的公共外展活动。

Technical: The overarching goal of this research project is to grow single crystals of binary compounds formed from organic or inorganic donors and acceptors, to explore their physical properties, and to identify the most promising candidate materials for potential applications for electronics and optoelectronics. The project brings together a unified group of scientists, from several campuses, with extensive knowledge and experience in the materials growth, materials characterization, device behavior, and theory of organic semiconductors. The team will concentrate its efforts on organic binary charge-transfer compounds composed of two different organic molecules in which one molecule acts as a donor and the other as an acceptor. A transition from research on single-component materials to that of binary- and multi-component materials offers the prospect of the discovery of unexpected material properties and new phenomena, as the intermolecular interactions between donor and acceptor molecules (with electron transfer playing the critical role) allow for novel functionalities.Nontechnical: The project addresses basic research issues in a topical area of materials science. The study of new binary organic compounds has the potential to move the field of organic semiconductors forward in a significant way, by opening up a large range of functionalities not manifest in monomolecular solids and creating new applications for electronics and optoelectronics. The graduate students who participate in this project will gain broad experience in a range of physical characterization techniques, device fabrication and characterization, quantum-chemical computational methods, and crystal growth. Undergraduates will experience exciting collaborative and interdisciplinary topics of research and a stimulating environment for training. The research results will be integrated into courses taught by the co-PIs at the undergraduate and graduate level, including special-topics courses on organic electronic materials and devices. They will also be used in public outreach activities sponsored by local science museums.
