    Merits of high resolution electron microscopy in the study of alloy structures (1986)
    New York, NY : Wiley-Blackwell
    Journal of Electron Microscopy Technique 3 (1986), S. 57-66

    ISSN: 0741-0581

    Topics: Natural Sciences in General
    Notes: We found that high resolution electron microscopy has the following merits in the study of alloy structures: (1) New phases too small to be studied by x-rays, such as σ-related phases, may be studied; (2) local and highly disordered structures, such as domain boundaries and domains of only a few unit cells, are more easily studied; and (3) it is easier to order solute atoms, such as Ti atoms columns in Cu4Ti.

    High-resolution electron microscopy of high-temperature superconductors (1988)
    New York, NY : Wiley-Blackwell
    Journal of Electron Microscopy Technique 8 (1988), S. 297-306 
    Details
    ISSN: 0741-0581
    Keywords: Defects ; Polymorphs ; Structure ; Life and Medical Sciences ; Cell & Developmental Biology

    Topics: Natural Sciences in General
    Notes: We review recent results obtained at Northwestern using high-resolution electron microscopy to study high-temperature superconductors. While in general these materials form large, very perfect single crystal grains which display very few imperfections, there is also evidence of slip defects, amorphous regions, and order-disorder transformations. We also report that the gadolinium-based superconductors and in one case yttrium-based superconductors show evidence for some copper solid solubility in the form of copperrich planar defects. The structure of a metastable trigonal polytype is also reported, as are the effects of electron beam and water vapor damage to the materials.
