Application:
XPS (X-ray Photoelectron Spectroscopy) or ESCA (Electron Spectroscopy for Chemical Analysis), is the most important method of all surface analysis techniques. Elemental and chemical information about the top few atomic layers can be obtained with ease from insulating as well as conducting materials. Each element has a finger print spectrum and when several elements are present on the same surface, these can be clearly identified and their chemical states ascertained from their photoelectron binding energies. It is widely used as a major tool in the surface analysis of materials and chemistry.
