Probing Interfacial Structure and Composition with X-Ray Standing Waves.

摘要

A brief description is given for the principles of x-ray standing waves based on Bragg diffraction and total external reflection. The broad range applicability of this technique to probe interfacial structure and composition is illustrated by considering representative examples from the areas of adsorbate structures in ultra-high vacuum, potential dependent changes in an electrochemical systems and the study of ionic distributions at a model membrane.
