Effect of Oriented Defects on Long-Range Ordering of Hydrocarbon Films: Azulene on Pt(111)

摘要

Low energy electron diffraction has been used to investigate the effect of ion bombardment-induced defects on the long-range ordering of azulene molecules absorbed on Pt(111). Such defects can lead to preferred directional ordering of the organic film. This is demonstrated by the stabilization of certain domains over others which are energetically equivalent on the defect-free surface.
