Variable-angle high-angle annular dark-field (HAADF) imaging in scanning transmission electron microscopy is developed for precise and accurate determination of three-dimensional (3D) dopant atom ...
We compared the two-dimensional difference-filtered (2D-DF) HAADF–STEM images with the simulated STEM images obtained from our proposed 6M-TTP cluster along [100], [110] and [111] zone axes, ...
The discovery announced in Science by Harmer's group sheds light on the atomic structures that form when atoms segregate at general grain boundaries, which are important in controlling many properties ...
There is a correlation between bulk mechanical properties of polycrystalline materials and the strength of individual grain boundaries at the micro- or nano-scale. The strength of the grain boundary ...
