Cluster Imaging with a Direct Detection CMOS Pixel Sensor in Transmission Electron Microscopy
نویسندگان
چکیده
A cluster imaging technique for Transmission Electron Microscopy with a direct detection CMOS pixel sensor is presented. Charge centre-of-gravity reconstruction for individual electron clusters improves the spatial resolution and thus the point spread function. Data collected with a CMOS sensor with 9.5×9.5 μm pixels show an improvement of a factor of two in point spread function to 2.7 μm at 300 keV and of a factor of three in the image contrast, compared to traditional bright field illumination.

متن کاملCMOS Pixel Sensor Response to Low Energy Electrons in Transmission Electron Microscopy
This letter presents the results of a study of the response of a test CMOS sensor with a radiation tolerant pixel cell design to 80 keV and 100 keV electrons. The point spread function is measured to be (13.0 ± 1.7) μm at 100 keV and (12.1 ± 1.6) μm at 80 keV, for 20 μm pixels. Results agree well with values predicted by a Geant-4 and dedicated charge collection simulation.
