Size and Shape of Nanoclusters: Single-Shot Imaging Approach
نویسندگان
چکیده
A method of single-shot imaging via aberration-corrected scanning transmission electron microscopy equipped with high angle annular dark-field detector (STEM-HAADF) has been applied to size-selected gold model catalysts (Au(25) and Au(39) ) on hydroxyapatite. Through quantitative intensity analysis, the size, in terms of number of atoms as well as 3D shape of the clusters are obtained.

متن کاملImaging the real shape of nanoclusters in scanning force microscopy
A quantitative comparison between experiment and theory is given for the constant height mode imaging of metal nanoclusters in dynamic scanning force microscopy. We explain the fundamental mechanisms in the contrast formation with the help of the system Pd/MgO 001 . The comparison shows that the shape and size of nanoclusters are precisely imaged due to the sharpness of the tip’s last nanometer...
