Electron techniques encompass a set of experimental methods that exploit the wave–particle duality and charge of electrons to probe, image, or modify matter at microscopic to atomic scales. Key modalities include electron microscopy (e.g., TEM, SEM, STEM), electron diffraction, and various electron spectroscopy techniques (such as AES and EELS), which rely on controlled electron beams and their interactions with atomic potentials, electronic structure, and surface topography. These techniques provide high spatial and energy resolution, enabling quantitative characterization of crystallography, composition, electronic states, and defects in materials, and are fundamental in condensed matter physics, materials science, nanotechnology, and surface science.
Using a unique combination technology, a team of researchers from Nagoya University in Japan has analyzed the mechanisms of the light-matter interaction in nanomaterials at the smallest and fastest levels.
