Defects Study in Gold Surfaces Produced by Ion Bombardment


We present new experimental results regarding the surface defect structure of ion bombarded gold surfaces. We report annealing mechanisms of surface defects on reconstructed Au(001) after medium fluence ion bombardment. We show how (001) and (111) gold surfaces can be nanostructured with a certain degree of lateral order by means of high fluence and high flux ion irradiation. We prove that ion irradiation nanostructuring strongly changes optical (plasmonic) properties of gold polycrystalline thin films.
