The positions of haadf stem intensity peaks in the perpendicular direction, averaged from multiple images, provide a valuable initial model for a rietveld refinement of the global c axis structure of the heterostructure. for an amorphous multi coat solution cast oxide sample, the analysis reveals statistically significant variations in the. K–l magnified haadf stem image and intensity profile of fe–cu atom pairs in the fepc@2d cu–n–c, simultaneously acquired haadf stem image with atomic resolution eels elemental mapping (cu. The tem, the high angle annular dark field scanning transmission electron microscopy images (haadf stem) and the corresponding eds mappings on the cross section of b sn a after the 3 h test in khco 3 clearly show the layered distribution of cu, sn, zn and o, where the pt is the protective layer used in the fib process (figure 2c,d). The bright field (bf) detector in stem, which is an on axis disk type scintillator, is used to collect the small angle elastically scattered electrons and can be regarded as the counterpart of the electron source in ctem. therefore, small angle stem bf imaging is the direct analogue to high resolution transmission electron microscopy (hrtem.
