Dependence of the adsorption height of graphenelike adsorbates on their dimensionality

Autor: Weiß, S., Gerbert, D., Hecht, S., Sokolowski, M., Tegeder, P., Soubatch, S., Tautz, F. S., Stein, A., Schenk, A. K., Yang, X., Brülke, C., Kremring, R., Feldmann, S., Posseik, Francois, Gille, M.

Comparing the adsorption heights of various graphene nanoribbons on Cu(111) and Au(111) surfaces to those of graphene and π-conjugated planar organic molecules, we observe that two-dimensional graphene adsorbs much further away from the surface than

Adsorption-induced symmetry reduction of metal-phthalocyanines studied by vibrational spectroscopy

Autor: Sforzini, Jessica, Posseik, Francois, Tautz, Frank Stefan

Publikováno v: Physical review / B 96(16), 165410 (2017). doi:10.1103/PhysRevB.96.165410

We investigate the vibrational properties of Pt- and Pd-phthalocyanine (PtPc and PdPc) molecules on Ag(111) with high-resolution electron energy loss spectroscopy (HREELS). In the monolayer regime, both molecules exhibit long-range order. The vibrati

Interaction of C$_{60}$ with clean and hydrogenated SiC-(3×3) probed through the unoccupied electronic states

Autor: Posseik, Francois, Ksari, Y., Lin, Y. P., Porte, L., Themlin, J.-M.

Publikováno v: Physical review / B 88(12), 125421 (2013). doi:10.1103/PhysRevB.88.125421

The effect of hydrogenation on the conduction bands of the Si-rich 6H-SiC(0001)-(3×3) reconstruction is studied using inverse photoemission spectroscopy in order to distinguish surface from bulk states. These results are exploited for the comparativ

High-temperature desorption of C60 covalently bound to 6H-SiC(0001)-(3x3)

Autor: Posseik, Francois, Ksari, Y., Giovanelli, L., Porte, L., Themlin, J.-M.

Publikováno v: Physical review / B 84(7), 075333 (2011). doi:10.1103/PhysRevB.84.075333

The desorption or fragmentation temperature of C-60 bound to Si-rich-(3 x 3) and (root 3 x root 3) R30 degrees. reconstructions of 6H-SiC(0001) is investigated using inverse photoemission spectroscopy (IPES) and LEED experiments. On SiC-(3 x 3), C-60
