摘要：

Lines of diffraction contrast have been observed near the interfaces of epitaxial layers of III-V compounds in transmission electron microscope samples cut perpendicular to the growth plane. The contrast occurs even for extremely small misfits. To explain the origin of these diffraction contours, a numerical stress analysis was carried out and the diffraction contrast was calculated using the dynamical theory of image contrast. © 1979.
