Accelerating Nanoscale Materials Characterisation Using Seamless 4D-STEM Workflows – TESCAN TENSOR Analytical STEM

Seminar/Demonstration

TESCAN’s new TENSOR 4D-STEM is revolutionising how materials can be characterised at the nanoscale. By designing the system from the ground up for performance and usability, precise, multimodal 4D-STEM structural and analytical measurements are within the reach of all users and are not limited by conventional TEM designs.

Full integration and synchronisation of state-of-the-art components such as a large direct electron detector with hybrid pixel technology, electron beam precession, electrostatic beam blanker and large dual EDS detectors maximises throughput of STEM, EDS and 4D-STEM measurements. The included ExploreTM software package streamlines workflows allowing data acquisition, analysis and visualisation in almost real-time resulting a optimised user expereiences.

Furthermore, a novel approach to analytical STEM measurement allows users to generate STEM, 4D-STEM, EDS and tomographic data as if they were using a SEM or FIB/SEM, unlike other approaches that rely on complex TEM training. This opens doors for nanoscale research in multimodal, nanoscale morphological, chemical, and structural characterisation of functional materials, thin films, and synthetic and natural crystals.

LiTi2PO43 structure determined using TESCAN TENSOR 4D-STEM
Precession assisted 4D-STEM phase and orientation maps for the LiTi2(PO4)3 (Green), TiO2 (Red) with their respective orientation legends. The LiTiOPO4 minority phase is shown in cyan (highlighted in circles), but is not of interest for orientation studies. Example indexed diffraction patterns from each phase are shown.
