| 요약≠ | Energy-Dispersive X-ray Spectroscopy (EDS) is an analytical technique that identifies and quantifies chemical elements in microvolumes of samples by analyzing characteristic X-rays emitted during electron bombardment. Rooted in Moseley's discovery of characteristic X-ray lines in 1913 and developed as a practical microanalytical tool by the 1970s, EDS is integrated into scanning electron microscopes (SEM) and transmission electron microscopes (TEM) for spatially-resolved elemental analysis. It is indispensable in materials characterization for phase identification, compositional mapping, and alloy development. | X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is a surface-sensitive analytical technique that measures the kinetic energies of photoelectrons ejected from a material by high-energy X-rays. Developed by Kai Siegbahn in 1967, XPS determines elemental composition, chemical oxidation states, and chemical bonding within ~10 nanometers of a surface. It is indispensable in materials science for surface characterization, corrosion studies, oxide analysis, and interface chemistry. |
