For the 0.22 µm nanopattern, which cannot be identified in the fluorescence images, the topography images taken on the same

Moreover, how do charge compensation mechanisms act at interfaces? What is the result of the “polar discontinuity” and of the presence of

• Co3O4(111) films with the spinel structure [13][14] show evidence for an apparently unreconstructed (1×1) surface, the stability of which was proposed to be based on a Co2+/Co3+ inversion process leading to charge compensation. In the present case of MgAl2O4(111), no previous experimental studies are
