Auger Electron Spectroscopy of Au(111) Films

In thin metal films, the predominant model used to explain adsorbate induced changes to resistivity is the Free Electron Point Scatters (FERPS) model. Previous experiments where dimethyl sulfide was thought to have adsorbed onto Au(111) thin films that were cleaned with argon ion sputtering and annealing failed to show the predicted change in resistivity.  Current research using Auger spectroscopy has revealed that the sample surface was likely contaminated with carbon such that no dimethyl sulfide had adsorbed.
