We present a study of the preparation procedure for stepped MgO surfaces which can be used as templates for the deposition of metallic nanostructures. A cleaved sample of MgO(001) was mechanically polished to reach the desired miscut angle along the [110] direction. Then a thermal annealing was performed. The effect of an intermediate chemical etching has been also studied. The surface was analyzed...
The interplay between swelling and milling phenomena in determining the morphology of Focused Ion Beam (FIB) -processed MgO(001) was investigated by atomic force microscopy. At the early stages of ion irradiation, before milling erosion is observed, MgO shows a relevant swelling behaviour with protrusion of the bombarded areas up to 6nm for a dose of 5×10 16 ionscm −2 . The effect...
