Atomic-scale Surface Investigations of Metal Oxide Single Crystals, Thin Films, and Nanostructures

在分析和表面化学项目的支持下，迪堡教授和她在杜兰大学物理系的同事正在研究表征良好的氧化物表面的表面化学。 使用扫描隧道显微镜，光电子能谱，和吸附的研究，SnO2，In2O3，和ZnO表面的几何和电子结构进行检查。 工作的重点是在一定条件下形成的这些材料的氧化物纳米带的结构和化学性质。 这些纳米带材料的合成和表征进行。 小分子在这些表面上的吸附和反应也进行了研究。 纳米氧化物材料的表面性质是本研究项目的重点，该研究项目由分析和表面化学计划支持。 使用扫描探针显微镜和光电发射方法，Diebold教授和她的合作者正在研究锡，铟和氧化锌表面的详细几何和电子结构，特别是在表现出纳米带结构的形态中。 小分子在这些表面上的吸附和反应也进行了研究。 从这些研究中获得的信息将有助于理解催化过程和纳米材料合成方法。

With the support of the Analytical and Surface Chemistry Program, Professor Diebold and her coworkers in the Department of Physics at Tulane University are studying the surface chemistry of well characterized oxide surfaces. Using scanning tunneling microscopy, photoemission spectroscopy, and adsorption studies, the geometric and electronic structure of SnO2, In2O3, and ZnO surfaces are being examined. Focus of the work is on the structural and chemical properties of oxide nanobelts of these materials formed under certain conditions. Both synthesis and characterization of these nanobelt materials is carried out. Adsorption and reaction of small molecules on these surfaces is also examined. The surface properties of nanoscale oxide materials are the focus of this research project supported by the Analytical and Surface Chemistry Program. Using scanning probe microscopy and photoemission methods, Professor Diebold and her collaborators are examining the detailed geometric and electronic structure of tin, indium, and zinc oxide surfaces, particularly in morphologies exhibiting nanobelt structures. The adsorption and reaction of small molecules on these surfaces is also examined. Information from these studies will be of use in the understanding of catalytic processes and nanomaterials synthesis methods.
