Scanning Tunneling Microscopy Studies of Alcohol/Alkane Mixtures Adsorbed on Graphite Surfaces
Mixtures of triacontanol/triacontane adsorbed on graphite surfaces have been investigated using STM in order to understand the relative importance of functional groups in determining the adsorbate/surface sticking probability. The images observed for these mixtures indicate that the alcohol and alkanes form separate regions on the surface and that the sticking probability is dependent on the liquid phase environment above the graphite surface. The mixtures exhibit interesting reorganization dynamics during which the alcohols and alkanes separate out on the surface.
