Abstract Scope Transmission Kikuchi diffraction (TKD) is maturing as an alternative technique to investigate crystal orientation of nanocrystalline materials. The improved spatial resolution in comparison to EBSD enables revealing the missing details of some microstructure, and finally achieve high-spatial resolution orientation maps of nanocrystalline materials in the SEM. As the interest in applying TKD increases, it becomes important to discuss some challenges, such as, charging, drift, carbon contamination spatial resolution and depth resolution. In this presentation, we will first focus on describing these challenges and present solutions to reduce/avoid them to obtain high-resolution TKD mapping of nanoparticles. Furthermore, we will demonstrate the improvement in lateral spatial resolution achieved in immersion mode and present the perspectives of blocking the saturated signal of the transmitted beam on the on-axis TKD detector to obtain diffraction patterns containing high contrast Kikuchi band and spot patterns simultaneously.
