A £3 million electron microscope has arrived at the University of Oxford's Department of Materials. The microscope will support research across the university's departments and divisions. It was ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...
