Cowley] Electron diffraction patterns may be obtained from regions 1 nm or less in diameter when a field-emission gun is used to form a very small bright source, as is usual in scanning transmission electron microscopy (STEM) instruments. Because the beam incident on the specimen can be assumed to be completely coherent, interference fine structure is visible in the patterns and provides the basis for deriving more detailed information on the specimen structure. For large angles of incident beam convergence, the diffraction patterns can be interpreted as in-line electron holograms. It has been proposed that the nanodiffraction patterns from each pixel of a STEM image should be combined to greatly enhance the image resolution. © 1996 Oxford University Press Articles nationallicence electron nanodiffraction nationallicence coherence nationallicence electron holography nationallicence ptychography nationallicence carbon nanotubes nationallicence Microscopy Oxford University Press 45/1(1996-02), 3-10 0022-0744 45:1<3 1996 45 jmicro https://doi.org/10.1093/oxfordjournals.jmicro.a023409 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/oxfordjournals.jmicro.a023409 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Cowley J.
