这项建议汇集了来自表面物理、表面化学、材料科学和陶瓷工程领域的跨学科研究小组，以研究氧化物表面的基本性质及其与金属覆盖层的相互作用。这项研究与当前和未来的技术相关。氧化物材料的应用范围包括用于磨损或结构用途的陶瓷材料、用于光纤和通信的非晶态氧化物、化学和生物传感器、复合材料、催化剂和新型高温超导材料。这项研究的目的是识别和了解影响氧化物表面金属覆盖层的吸附、成核和生长的关键表面属性。主要的科学重点将是(1)在特征良好的氧化物表面形成金属覆盖层，(2)结构氧化物的金属化，以及(3)在无定形氧化物和硅酸盐上的金属吸附和覆盖层生长。

This proposal brings together an interdisciplinary group of investigators from the fields of surface physics, surface chemistry, materials science, and ceramics engineering to study fundamental properties of oxide surfaces and their interactions metal overlayers. This research is relevant to current and future technology. The spectrum of applications of oxide materials includes ceramic materials with desirable properties for wear or structural use, amorphous oxides for fiber optics and communications, chemical and biological sensors, composites, catalysts and the new high temperature superconducting materials. The goal of the research is to identify and understand the key surface properties that affect the adsorption, nucleation, and growth of metal overlayers on oxide surfaces. The major scientific emphasis will be on (1) metal overlayer formation on well characterized oxide surfaces, (2) metallization of a structural oxide, and (3) metallic adsorption and overlayer growth on amorphous oxides and silicates.
