Probing complex adsorbate systems using Angle-Resolved NIXSW — •Gerben van Straaten, Markus Franke, and Christian Kumpf — Peter Grünberg Institute (PGI-3), Forschungszentrum Jülich and Jülich Aachen Research Alliance (JARA) – Fundamentals of Future Information Technology (FIT), 52425 Jülich, Germany

The Normal Incidence X-ray Standing Waves (NIXSW) technique is a popular and very efficient technique for studying adsorbate structures, but unfortunately, it is only of limited use when adsorbate atoms display a range of adsorption heights. In this presentation we show that angle-resolved NIXSW measurements can take advantage of the limited mean-free path of photoelectrons and that more information about the adsorbate distribution can be obtained. This can be used to study vertical disorder in monolayer structures.
