This project will consist of the modification of solid surfaces by alkali metal overlayers. The project focuses on investigating the electronic promotion of surface chemical reactions and the modifications of the electronic structure of several technologically important semiconductors by alkali overlayers. Experimentally, the project is based on the well proven technique of photoemission spectroscopy using the soft x-ray spectrum provided by the new high brilliance 1 GeV electron storage ring at the Synchrotron Radiation Center of the University of Wisconsin.

该项目将包括用碱金属覆盖层对固体表面进行改性。该项目的重点是研究表面化学反应的电子促进以及碱覆盖层对几种具有重要技术意义的半导体的电子结构的改变。在实验上，该项目是基于威斯康星大学同步辐射中心新的高亮度1GeV电子存储环提供的软X射线能谱，这是一项得到充分验证的光电子能谱技术。
