报告题目(中文)：电子探测器及在4D-STEM（扫描透射电子显微镜）上的应用

报告题目(英文)：Electron detectors and 4D STEM applications

报告内容简介：

The first part of the presentation will offer a brief summary of electron detector technologies and outline their respective strengths and weaknesses. There will be a detailed description of the hybrid pixel technology, specifically exploring the thresholding and counting concept. The second part of the presentation focuses on the practical utilization of a state-of-the-art hybrid pixel 4D STEM detector. Results are presented for various 4D STEM techniques, including virtual detectors, center-of-mass analysis, ptychography and orientation mapping.
