Interfacial Chemistry of Organic Molecules and Self- Assembled Organic Layers on Si(001) Surfaces

本研究项目由分析与表面化学计划资助，主要研究了Si（001）表面与不饱和有机分子通过2+2环加成反应的情况。 威斯康星州大学的Hamers教授和他的学生将使用扫描探针显微镜、傅里叶变换红外光谱、拉曼光谱和X射线光电子能谱来研究通过这种途径形成的有序有机膜。 这些有机膜可以衍生化，并开发功能策略以形成具有特定电子和光学性质的覆盖层。 这些薄膜的化学和结构性质与有趣的电学和光学性质的可能性相关。 用于表征这些覆盖层的空间相关探针允许确定预期出现的空间各向异性。 不饱和有机分子在硅表面的吸附是本项目支持的研究重点。 开发硅上有机膜的灵活合成化学的能力有望将电子器件的硅工艺技术与有机覆盖层的广泛性能联系起来。 一系列的空间依赖性的方法将被用来表征这些合成覆盖层的结构和性能。

The reaction of the Si(001) surface with unsaturated organic molecules via a 2+2 cycloaddition is studied in this research project supported by the Analytical and Surface Chemistry Program. Professor Hamers and his students at the University of Wisconsin will study ordered organic films formed by this route using scanning probe microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. These organic films can be derivatized, and functional strategies developed to form overlayers with specific electronic and optical properties. The chemical and structural properties of these films are correlated with the possibility of interesting electrical and optical properties. The spatially dependent probes used to characterize these overlayers allow the determination of the spatial anisotropy which is expected to arise. The adsorption of unsaturated organic molecules on the silicon surface forms the focus of the research supported in this project. The ability to develop a flexible synthetic chemistry for organic films on silicon promises to allow the connection of silicon process technology for electronic devices with the broad range of properties possible with organic overlayers. A range of spatially dependent methods will be used to characterize the structure and properties of these synthesized overlayers.
