A model poly-epoxy surface formed by the reaction of DGEBA and EDA is studied by the combination of experiments and DFT calculations. A special synthesis protocol is presented leading to the formation of a surface that is smooth (Sa<1nm), chemically homogeneous, and that presents a low-defect density (0.21μm−2), as shown by AFM characterizations. Then, XPS is used for the determination of the elemental...
The morphological evolution on Si (100) surface for grazing incidence (75°) and low energy (500eV) Ar+ sputtering is studied at various ion fluences. The ion induced surface topography was characterized by atomic force microscopy. Initially ion sputtering generates irregular dot-like structure on the surface. These dots begin to elongate along the ion beam direction with the increase of sputtering...
