• ) operating at 300 kV in the scanning mode (STEM). The images were acquired using a mass sensitive high annular dark-field detector (HAADF, type Fischione) resulting in a resolution of < 0.135 nm. Images were evaluated by the use of the program ImageJ. The diameters of the particles in the saturation state

Although it was not possible to resolve such a CoO layer from the high-resolution TEM images (Figure 2), dark-field TEM images (Figure 4a) reveal the presence of a crystalline ~4 nm thick layer being well distinguishable from
