A NIXSW and NEXAFS investigation of thiophene on Cu (111)
P Milligan, J McNamarra, B Murphy, BCC Cowie… - Surface science, 1998 - Elsevier
The local registry and geometry of thiophene at sub-monolayer coverages on Cu (111) has
been probed with normal incidence X-ray standing wavefield absorption (NIXSW) and near
edge X-ray absorption fine structure (NEXAFS). Thiophene was found to adopt a flat
geometry on the surface with the sulphur atom in an atop position. The relatively short data
collection times required for the NIXSW technique were found to be beneficial when looking
at thiophene overlayers which are sensitive to X-ray induced damage.
