The electronic structure of germanene is investigated by high resolution photoemission and density functional theory calculations. The core level Al 2p and Ge 3d lines are measured on germanene grown on Al(111) by using synchrotron radiation. The Ge

Germanene, a 2D honeycomb structure similar to silicene, has been fabricated on Al(111). The 2D germanene layer covers uniformly the substrate with a large coherence over the Al(111) surface atomic plane. It is characterized by a (3 × 3) superstruct

The grafting of trialkoxysilane molecules should also give rise to the formation of a siloxane network at the substrate's surface when trialkoxysilanes are used. Other candidates that might be able to act as adhesion promoters at metallic surfaces ar

We report here on the atomic migration and associated nucleation mechanisms of Si nanocrystals on LaAlO 3 (001) surface, a high-κ crystalline oxide. Chemical and structural properties were investigated using X-ray photoelectron spectroscopy, X-ray p

Non-volatiles flash memories embedding nanocrystals are promising devices. These memories are made of semiconducting or metallic nanostructures inserted in an insulating matrix. SiO2, traditionally used as an insulator, is gradually replaced by high-

Fe deposits were performed on LaAlO3 (001) by molecular beam epitaxy at different substrate temperatures. Chemical and structural characterizations were carried out in-situ, by X-ray photoelectron spectroscopy (XPS), reflection high-energy electron d

In order to facilitate its incorporation into a polymer matrix (mostly hydrophobic), calcium carbonate (CaCO3), which is strongly hydrophilic, has to be chemically treated to avoid the formation of aggregates and to improve the compatibility with the

We report on the initial growth mechanisms of Ge on LaAlO3(0 0 1), a crystalline oxide with a high dielectric constant (high-κ material). Chemical and structural properties were investigated in situ, through X-ray photoelectron spectroscopy and refl
