poster session 9 - poster ID IMP3.P22
Our poster at MC2025 in Karlsruhe presents a novel technique to improve electrical analysis (EA) of integrated circuits (ICs) using electron microscopy, where traditional methods struggle to measure extremely low pA-level currents due to noise and beam limitations. It introduces a lock-in amplification strategy that modulates the electron beam using existing scan coils - rather than specialized beam blankers - to produce a clean, noise-reduced signal. This approach significantly reduces low-frequency noise in resistive contrast imaging (RCI), especially for low-ohmic devices, enabling faster and more reliable mapping.

poster session 2 – poster ID IMP1.P15
The poster at MC2025 in Karslruhe by Lewys Jones from Trinity College Dublin, presents a new scanning strategy for Scanning Transmission Electron Microscopy (STEM) aimed at achieving much higher imaging speeds - towards 50 fps with ~50 ns per pixel with fully sampled images - on existing systems. Traditional scan methods faced limitations due to flyback distortions and hardware constraints, but the proposed serpentine scan pattern and overdrive correction mitigate these issues by smoothing beam motion and correcting for non-linearities. This approach enables faster, distortion-corrected imaging without requiring new hardware, making high-speed STEM more accessible. The experiment setup included the point electronic DISS6 SEM scan controller.

In situ and operando electron microscopy investigation of Pt surface dynamics under H₂ and O₂ environments

poster session 21 - poster ID MS7.P29
This poster at MC2025 in Karlsruhe by Meimei Wang, Technical University of Munich, presents the analysis of a catalyst surface restructuring during high-temperature reactions using operando scanning electron microscopy (SEM) to study Pt/Rh catalysts relevant to ammonia oxidation. By combining secondary electron, absorbed current, and high-temperature backscattered electron imaging with EBSD, the researchers track real-time grain orientation-dependent surface changes under controlled H₂/O₂ atmospheres. This electron microscopy approach enables detailed analysis of restructuring dynamics, volatile species formation, and morphology evolution, providing insights into catalyst degradation mechanisms and guiding future improvements.
