CalAtom: A software for quantitatively analysing atomic columns in a transmission electron microscope image.
TL;DR: The CalAtom software is developed for quantitative analyses of atomic columns in (scanning) transmission electron microscopy, (S)TEM, images and offers several options for further analyses, such as in-plane scale local environments of the atomic columns, local elementary composition and real-space averaging of image motifs.
Journal ArticleDOI
Structure projection reconstruction from through-focus series of high-resolution transmission electron microscopy images
TL;DR: A structure projection reconstruction method based on contrast transfer function correction of through-focus series of high-resolution transmission electron microscopy images is presented and Influences of experimental parameters for imaging and effects of crystal thickness on reconstruction are discussed.
Journal ArticleDOI
Recombination of Shockley partial dislocations by electron beam irradiation in wurtzite GaN
TL;DR: In this article, the authors used high-resolution transmission electron microscopy (HRTEM) image simulations, in conjunction with density functional theory calculations, led to the identification of the core structures of the Shockley partials.

TL;DR: A novel algorithm to numerically retrieve the phase of the exit-wave function from a high-resolution transmission electron microscopy (HRTEM) image of a weak-phase object material, e.g., graphene and hexagonal boron nitride monolayers is proposed.
Journal ArticleDOI
A quantitative method for measuring small residual beam tilts in high-resolution transmission electron microscopy.
TL;DR: A quantitative method for measuring small residual beam tilts, being independent of specimen thickness and taking specimen drifts into account in measurement, is reported, including its theoretical schemes, numerical simulation testing and experimental verification.

Fabrication of a freestanding boron nitride single layer and its defect assignments.
TL;DR: A freestanding single layer of hexagonal boron nitride (h-BN) has been successfully fabricated by controlled energetic electron irradiation through a layer-by-layer sputtering process and the dominating zigzag-type edges are proved to be nitrogen terminated.
