A UHV Surface Analysis System for Nonlinear Optical Studies of Surface Structure, Spectroscopy and Dynamics

对表面非线性光学现象的认识及其作为表面物理化学性质探针的应用，将对表面科学、材料加工以及光学和电子器件的发展产生根本性的影响。使用最先进的表面处理技术，加上精密的激光仪器和适当的表面分析系统，提高了研究人员在与激光相互作用之前、期间和之后获得表面详细信息的能力。该奖项由化学共享仪器计划和材料研究仪器计划共同支持，将有助于获得超高真空(UHV)表面分析系统的主要部分。此次收购将增强的领域包括：1)强光与吸附物和表面的相互作用。2)近自由电子(NFE)金属的电子结构，特别是表面附近的电荷密度。3)发展了用于研究表面脱附动力学、能量传递和反应动力学的快速时间分辨方法。

The knowledge of nonlinear optical phenomena at a surface and their use as probes for surface physical and chemical properties will have fundamental impact on surface sciences, materials processing, and development of optical and electronic devices. The use of state-of-the-art surface preparation coupled with sophisticated laser instrumentation and the appropriate surface analysis system enhances the ability of investigators to obtain detailed information on the surface before, during, and after interaction with the laser light. This award, co-supported by the Chemistry Shared Instrumentation Program and the Instrumentation for Materials Research Program, will aid in the acquisition of the major portion of an Ultra High Vacuum (UHV) Surface Analysis System. The areas that will be enhanced by the acquisition are: 1) The interaction of intense light with adsorbates and surfaces. 2) The electronic structure of nearly free electron (NFE) metals, particularly the charge density near surfaces. 3) Development of fast time-resolution for the study of desorption dynamics, energy transfer, and reaction dynamics on surfaces.
