X-ray Photoelectron Spectroscopy. X-ray Photoelectron Spectroscopy (XPS), also known as ESCA, is a surface analysis technique that uses an x-ray beam to eject electrons from a kinetic energies of the ejected electrons (photoelectrons) are then analyzed to produce a spectrum, in which photoelectron peaks coming from different chemical elements can be identified by their. X-Ray photoelectron spectroscopy also termed as electron spectroscopy for chemical investigation is widely used to investigate chemical proportion of surfaces. The proliferated use of XPS in investigative laboratories across the globe acts as a problem solving capability of the technique.

van Attekum. X-Ray Photoelectron Spectroscopy (XPS) is based on the photoelectric effect, which was first discovered by Albert Einstein in The photoemission process from a solid sample takes place when a highly energetic photon interacts with matter, causing an electron to be removed from an atomic orbital or from a band and to reach the vacuum excitation energy must be large enough for the.
Introduction. This chapter specializes in quality use of X-ray photoelectron spectroscopy (XPS) to characterize carbonaceous materials. For information about theoretical and fundamental aspects, instrumentation, and more, many published books and references are available. In addition, since innumerable articles concerning carbonaceous materials and XPS have been published, references Cited by: 1.
