Structure determination of silicene nanoribbons on Ag(110)

Espeter P., Keutner C., Kleimeier N.F., Roese P., Shamout K., Wenzel G., Berges U., Zacharias H., Westphal C., TU Dortmund, DE

Since the discovery of graphene much interest came up in the graphene analoga from the carbon group. One of the most famous representatives is silicene. Silicene is known to crystallize in different configurations, depending on [...]

Insight into bacteria: magnetosomes chains under photoemission electron and scanning electron microscopes

Keutner C., von Bohlen A., Berges U., Espeter P., Schneider C.M., Westphal C., TU Dortmund University, DE

Magnetotactic bacteria (MTB) are forming magnetosome chains consisting of greigite or iron oxides. In technological, medical, and environmental applications magnetosomes are considered as perspective material. Among all techniques applied to MTB, two providing spatial, chemical, [...]

Investigation of the MgO absorbate and the MgO/Fe on GaAs(001) surface by means of XPS and XPD

Handschak D., Schönbohm F., Lühr T., Keutner C., Berges U., Westphal C., TU Dortmund, DE

We report a combined high-resolution photoemission and photoelectron diraction investigation of a magnesium oxide adsorbate on an Fe surface grown on a GaAs(4x2)-reconstructed substrate. MgO is an appliciable insulator in magnetic tunnel junctions (MTJ) based [...]
