Orientation Of Nickelocene On Ag(100), D. L. Pugmire, C. M. Woodbridge, Marjorie Langell

Marjorie A. Langell Publications

High-resolution electron-energy-loss spectroscopy has been used to study the molecular adsorption of nickelocene, Ni(C₅H₅)₂, on Ag(100). Results indicate that at up to one monolayer coverage, nickelocene adsorbs molecularly with its axis approximately perpendicular to the surface. At very high coverages, the molecular axis is not exclusively oriented along the surface normal. This is possibly due to randomization of the metallocene orientation as multilayers are formed.
