WebEnergy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. A sample excited by an energy source (such as the electron beam of an electron microscope) dissipates some of the absorbed energy by ejecting a core-shell electron. WebAs a result, TEM. offers invaluable information on the inner structure of the sample, such as crystal structure, morphology and stress state information. f Scanning Electron Microscopy. The scanning electron microscope (SEM) produces images by scanning the sample with a high-. energy beam of electrons.
