Orientation Mapping via Dictionary Indexing of AC-STEM Kikuchi patterns using Open-source Software
Shamail Ahmed, Johannes Haust, Felix Gruber +5
The properties of polycrystalline materials are strongly influenced by the spatial arrangement and orientations of individual grains within the microstructure, making nanoscale cha…
Low Temperature MOCVD Synthesis of high-mobility 2D InSe
Robin Günkel, Oliver MaÃmeyer, Markus Stein +14
Two-dimensional (2D) indium selenide (InSe) is a layered semiconductor with high electron mobility and a tunable band gap ranging from 1.25 eV in the bulk to 2.8 eV in the monolaye…
Microstructure of Silicon Anodes in Solid-State Batteries -- From Crystalline to Amorphous
Shamail Ahmed, Federico Rossi, Hanyu Huo +6
Silicon offers great promise as a potential anode active material and the optimum alternative to lithium metal in all-solid-state lithium-ion batteries. However, its practical appl…
Determining the grain orientations of battery materials from electron diffraction patterns using convolutional neural networks
Jonas Scheunert, Shamail Ahmed, Thomas Demuth +4
Polycrystalline materials have numerous applications due to their unique properties, which are often determined by the grain boundaries. Hence, quantitative characterization of gra…
Sequential tilting 4D-STEM for improved momentum-resolved STEM field mapping
Christoph Flathmann, Ulrich Ross, Jürgen Belz +4
Momentum-resolved scanning transmission electron microscopy (MRSTEM) is a powerful phase-contrast technique that can map lateral magnetic and electric fields ranging from the micro…
