TECHNICAL SUMMARYThis project, supported by the Solid State and Materials Chemistry Program, aims to provide a new means of synthesizing and designing functional and stable inorganic-organic interfaces for exploitation across a wide range of applications, such as selective, high-sensitivity chemical and biological sensors and efficient photon harvesting platforms. The traditional synthesis approach for attaching molecular overlayers to semiconductors creates minimal modifications to the inorganic support except to 1) remove any surface oxide present pre-attachment, and 2) attach appropriate molecular linking groups, if needed. A key requirement for device exploitation is therefore the creation of a highly - dense overlayer that impedes re-oxidation of the interface. The goal of this project is to demonstrate the feasibility of using oxides designed as chemical templates that impact molecular attachment by inhibiting or enhancing different chemical reaction pathways. This approach will be used to ultimately create a stable, functional interface. An emphasis on determining the key chemical reactions governing cysteamine and succinic acid attachment to InAs, a model III-V semiconductor, is the focus of this effort with the goal of developing a follow-on application-focused materials/device proposal to NSF.NON-TECHNICAL SUMMARYInorganic-organic interfaces are the heart of a new generation of electronic and photonic devices. This research project aims to create more stable and higher performance interfaces designed for devices used in energy and sensing applications. The core of the effort is to design oxide interface materials that control the attachment of molecules to device surfaces yielding new performance regimes and higher reliability. The project marries the critical disciplines of chemistry, materials science, and engineering and, as such, students will derive considerable educational benefit from the experience gained working across these boundaries. This project involves collaboration between Prof. April Brown, Duke University, Dept. of Electrical and Computer Engineering, Dept. of Biomedical Engineering, and Dr. Maria Losurdo, CNR-Bari, Italy. The exchange of students between Duke and CNR in this multidiscipline effort also provides significant enhancements to their education.

在固态和材料化学计划的支持下，技术摘要项目旨在提供一种合成和设计功能和稳定的无机有机接口的新方法，以在广泛的应用中（例如选择性，高敏化的化学和生物学传感器以及高效的光子收获平台）进行开发。将分子叠加剂连接到半导体的传统合成方法对无机支撑的修改最少，除了1）消除任何表面氧化物目前的辅助前，以及2）如果需要，请连接适当的分子链接组（如果需要）。因此，设备开发的关键要求是创建高度 - 密集的叠加仪，阻碍了接口的重新氧化。该项目的目的是证明使用设计为化学模板的氧化物的可行性，这些氧化物通过抑制或增强不同的化学反应途径来影响分子附着。该方法将最终用于创建稳定的功能接口。强调确定控制西星的关键化学反应和III-V型半导体INAS的琥珀酸附着，这是这项工作的重点，其目的是为NSF开发以下申请的材料/设备建议。该研究项目旨在创建针对能源和传感应用程序中使用的设备设计的更稳定和更高的性能接口。努力的核心是设计氧化物界面材料，以控制分子在设备表面的附着，从而产生新的性能状态和更高的可靠性。该项目与化学，材料科学和工程学的关键学科结合，因此，学生将从这些界限中获得的经验获得可观的教育收益。该项目涉及生物医学工程部电气和计算机工程系April Brown教授与意大利CNR-Bari的Maria Losurdo博士之间的合作。在这项多学科工作中，杜克大学和CNR之间的学生交流也为他们的教育提供了重大增强。
