    Research outputpeer-review


    A study is made of the fringe patterns observed in transmission electron microscopy at antiphase boundaries or stacking faults with α=π . Use is made of the dynamic theory including anomalous absorption. The results are compared with observations of antiphase boundaries in titanium dioxide. The specific properties of the fringe patterns at π-boundarïes are discussed analytically and compared with those at 2π/3-boundaries
    From these considerations, criteria can be established which distinguish π-boundaries by their contrast features. Some computed profiles illustrate the agreement of this theory with observations on rutïle. A discussion is included of the fringe characteristics at the intersection of bend faults. Finally the contrast effects at parallel and intersecting overlapping faults are analysed.
    and intersecting overlapping fauits are analysed ^
