本项目主要通过电子显微镜和电子全息术研究金属氧化物的表面和界面。目标是解决在空气中表现出稳定重建的极性表面的原子结构，阐明这种不寻常的稳定性的原因，通过对不同氧化物的系统研究发现新的重建，探索这种重建是否能够促进新型外延膜的生长，以及探索这些极性表面是否具有有用的催化性能。该计划的教育部分将致力于融合电磁学、光学、量子力学、固体物理和表面科学的知识。这个项目的长期目标是在凝聚态物质的结构和性质方面形成一个综合的教育和研究计划。主题将是陶瓷表面和界面的结构。电子显微镜和全息摄影将是主要的实验方法。该项目的科学目标将是解决极性氧化物表面的原子结构，这些表面在空气中表现出不寻常的重建。在寻找新的表面重建的同时，本项目将试图阐明其稳定性的原因，并探索这种重建是否具有适合于催化和光电子应用的性质。＊＊＊

9553148 Gajdardziska-Josifovska This project focuses on the study of surfaces and interfaces of metal oxides by electron microscopy and electron holography. The goals are to solve the atomic structure of polar surfaces which exhibit reconstructions stable in air, to elucidate the reasons for this unusual stability, to discover new reconstructions via systematic study of different oxides, to explore if such reconstructions enable growth of novel epitaxial films, and tm explore if these polar surfaces have useful catalytic properties. The educational component of the program will aim towards fusion of knowledge from electromagnetism, optics, quantum mechanics, solid state physics, and surface science. %%% The long term goal of this project is to form an integrated educational and research program in structure and properties of condensed matter. The main theme will be structures of ceramic surfaces and interfaces. Electron microscopy and holography will be the primary experimental methods. The scientific goal of the project will be to solve the atomic structure of polar oxide surfaces which exhibit unusual reconstructions stable in air. While searching for new surface reconstructions, this project will attempt to elucidate the reasons for their stability and to explore if such reconstructions have properties suitable for application in catalysis and opto- electronics. ***
