EELS

Electron Energy Loss Spectroscopy (EELS) is an analytical technique that measures how electrons lose energy when they pass through a material. As high-energy electrons interact with the atoms in the sample, they can transfer energy to electrons or cause vibrations within the material. By analyzing the energy lost, scientists gain detailed information about the material's composition, structure, and electronic properties at a very small scale. EELS is often used in electron microscopes to study nanomaterials, thin films, and biological samples, providing insights that help in materials research, electronics, and chemistry.
