a) TEM image showing three colliding clusters. The scale bar is 10 nm. b) Relative positions of molecules derived from the X-ray diffraction crystal structure are overlaid (brown) on the TEM image.
and the diffraction pattern is recorded from that region. SAED is particularly useful for studying the local crystal structure, orientation, and phase identification of nanomaterials. CBED is another ...
