Adsorption and self-assembly of organic molecules at surfaces is a key issue in nanoscience and nanotechnology for the many possible uses of hybrid organic–inorganic interfaces. Depending on the nature of the molecules, applications are foreseen in the fields of molecular electronics, sensoristics, pharmacology, biocompatibility, hygiene and...

Ni nanoclusters up to 30 Å in diameter are grown by Ni deposition on ultrathin MgO/Ag(100) films at different temperatures and characterized by combining lowtemperature scanning tunneling microscopy with photoemission and vibrational spectroscopies. At 200 K, both small NixOy aggregates and 2D Ni nanoparticles of average size close to 12 Å...

When imaged by scanning tunneling microscopy (STM) at constant current under nontopographic conditions, nanosized MgO islands grown on Ag(100) may show a fractal dark internal structure and/or appear embedded in the surface. On the contrary, when imaged under topographic conditions, the same islands appear as nearly flat plateaus. Islands...

The chemical reactivity of single layers of supported graphene (G) is affected by the nature of the underlying substrate: in particular CO chemisorption occurs on G/Ni(111), while graphene on Cu is inert. Here, we demonstrate experimentally that doping of the G layer with nitrogen atoms further increases the reactivity of the G/Ni(111) system...
