Structure and Stability of Metal Surfaces: X-ray Experiments

这个项目的目标是开发一个微观的描述， 金属表面相行为，特别是在高温下 其中预期波动的作用是重要的。 通过 通过高分辨率X射线散射，研究人员将 研究粗糙化、金属刻面和表面熔化 重建和未重建表面的变换。 此外，还讨论了与之相关的二维相变。 将进行调查。 该计划将 有助于详细、微观地了解 真实的金属表面的统计物理学。 该司将特别 有助于我们理解金属表面的形态 与温度的关系，以及我们对 金属平衡晶体形状的行为。

The goal of this program is to develop a microscopic description of metal surface phase behavior, especially at elevated temperatures where the role of fluctuations is expected to be important. By means of high-resolution x-ray scattering, the researchers will investigate roughening, metal facetting and surface-melting transformations of both reconstructed and unreconstructed surfaces. In addition the two-dimensional phase transformations associated with reconstructions will be investigated. The program will contribute to a detailed, microscopic understanding of the statistical physics of real metal surfaces. In particular, it will contribute to our understanding of the morphology of metal surfaces versus temperatures and to our understanding of the thermal behavior of metal equilibrium crystal shapes.
