work in symmetry determination from convergent-beam ED. The new instruments could be used to record ED patterns from small areas of thin crystals, and in 1953, Cowley published the first crystal structure solution derived from single crystal electron diffraction data. This work was well ahead of its time; the technique did
Applications of electron nanodiffraction. J.M. Cowley*. Department of Physics and Astronomy, Arizona State University, P.O. Box 871504, Tempe, AZ 85187-1504, USA. Received 12 November 2003; revised 15 December 2003; accepted 16 December 2003. Abstract. Diffraction patterns from regions 1 nm or less in diameter
Key words: parallel electron diffraction, nanobeam, TEM/STEM, nanoparticles, nanowires, spot diffraction patterns the size of the diffrac- tion discs, thereby reducing disc overlaps. Cowley associated coherent electron nanodiffraction with STEM imaging and applied the technique to investigate the structure and sym-.
The Patterson method and model building were used for structure solution. Later, Dorset &. Hauptman (1976) showed that direct methods could also be used for phasing ED data. Cowley (1953a,b,c) performed structure analysis by electron diffraction before he developed the theory of multibeam dynamical scattering
31 Dec 1992 This two-volume work forms a comprehensive treatise on the theory and applications of electron-diffraction techniques, and has been organized under the auspices of the Electron Diffraction Commission of the International Union of Crystallography. The intended audience includes graduate students and

They addressed various problems which then could not be solved by X-ray diffraction, such had also been applied by Cowley in Melbourne for solving a few structures.
