High-precision texture analysis of Fe-Co metal thin films via deep-learning four-dimensional scanning transmission electron microscopy (opens in new tab)

The precise characterization of microstructure and nanotexture is crucial for tailoring the anisotropic functionalities of metallic thin films. In contrast to conventional analyses that address random grain orientation of polycrystalline films, this study focuses on sub-degree mistilt distributions and grain-boundary networks at the nanoscale while achieving spatially resolved mapping across entire films. We introduce a deep-learning-embedded four-dimensional scanning transmission electron mi...
