Desorption of silver atoms from benzene-covered Ag(111) by energetic Ar+ bombardment

Microscopic Insights into the Sputtering of Thin Organic Films on Ag{111} Induced by C60 and Ga Bombardment

“…Molecular dynamics (MD) computer simulations have successfully described the dynamics due to cluster bombardment on metal, graphite, and diamond surfaces, as mentioned above. In addition, these simulations have been employed to model the ejection of molecules from benzene overlayers on metal substrates where there are direct comparisons to experimental data of energy and angular distributions . Thus the MD method is utilized to elucidate the differences between Ga and C 60 bombardment of three layers of benzene on Ag{111}.…”

Internal Excitation Mechanisms of Neutral Atoms and Molecules Emitted from Ion Bombarded Organic Thin Films

“…12,13,15 Spectroscopic studies of molecules desorbed from organic monolayers have also emerged in the last several years. [16][17][18][19][20] In our lab, we have focused on benzene (C 6 H 6 ) adsorbed on Ag{111} as a model system. It is a particularly appropriate system since the adsorption of C 6 H 6 on Ag is reversible with temperature and C 6 H 6 does not form strong bonds with the Ag surface.…”
