“…The known structure of the surrounding matrix material proves to be highly advantageous in terms of enabling the objective lens defocus and the local specimen thickness to be determined accurately. Figure 12 shows an atomic-resolution electron micrograph of a 90 • twin boundary in YBCO-the image simulation (inset) again confirms the image interpretability in terms of the direct correspondence of the black-spot contrast to the projected metal cation columns (Barry and Anstis 1994). Similar grain boundaries in YBCO have been modelled during studies of thin-film step-edge junctions deposited on LaAlO 3 substrates .…”

The high-resolution electron microscope has evolved into a sophisticated instrument that is capable of routinely providing quantitative structural information on the atomic scale. Applications of atomic-resolution imaging can now be found in many scientific fields, and its impact on the knowledge and understanding of atomistic processes has been profound. Better control over instrumental parameters, enhanced reliability of signal recording, and novel methods for imaging and data processing are areas of highly active, ongoing research. Agreement over reliability factors, serious discrepancies in absolute contrast levels, and inversion of crystal scattering are identified as unresolved issues requiring further attention.
