Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

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 ...

A team of researchers has developed the first transmission electron microscope which operates at the temporal resolution of a single attosecond, allowing for the first still-image of an electron in ...
