Shape effect of microtwins on high‐resolution transmission electron microscope images

The shape effect of microtwins on high-resolution transmission electron microscopy (HRTEM) images is demonstrated with the help of a detailed comparison between experimental HRTEM images of recrystallized silicon (including many microtwins) and corresponding dynamical simulations. The analysis points to an important fact: The shape effect of microtwins leads to artificial contrasts. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
