The spatial resolution of core-loss imaging in the STEM

We have investigated the resolution of scanning transmission electron microscope images for single, isolated atoms. The images are simulated from first principles using a nonlocal model for electron core-loss spectroscopy. We have examined the role of the width of the probe in determining the locali...

Summary:We have investigated the resolution of scanning transmission electron microscope images for single, isolated atoms. The images are simulated from first principles using a nonlocal model for electron core-loss spectroscopy. We have examined the role of the width of the probe in determining the localisation of the images.
