Spektroskopia strat energii elektronów EELS (ang. Electron Energy Loss Spectroscopy) - odmiana spektroskopii elektronowej, polegająca na analizie rozkładu energetycznego elektronów rozproszonych niesprężyście. Elektrony przechodzące przez próbkę są rozdzielane w zależności od ilości utraconej energii. Widmo EELS może być ...
The electron energy loss (EEL) spectrum (sometimes spelled EELS spectrum) can be roughly split into two different regions: the low-loss spectrum (up until about 50 eV in energy loss) and the high-loss spectrum.
Within the last 30 years, electron energy-loss spectroscopy (EELS) has become a standard analytical technique used in the transmission electron microscope to extract chemical and structural information down to the atomic level.
1 paź 2000 · Electron energy-loss spectroscopy (EELS) in the transmission electron microscope is a powerful technique for measuring the valences of some transition metal elements of practical importance.
Electron energy-loss spectrometry (EELS) is the analysis of the energy distribution of electrons that have interacted inelastically with the specimen. These inelastic collisions tell us a tremendous amount about the electronic structure of the specimen atoms, which...
1 sty 2011 · Electron energy-loss spectroscopy (EELS) involves analyzing the energy distribution of initially monoenergetic electrons after they have interacted with a specimen. This interaction is sometimes confined to a few atomic layers, as when a beam of low-energy (100–1000 eV) electrons is “reflected” from a solid surface.
Chapters 1 to 6 develop the princi-ples of electron energy loss methods that are common to all materials studies. The remainder of the book, Chapters 7 to 12, focus on applications of EELS to particu-lar classes of materials—minerals, ceramics, catalysts, metals, magnetic materials, semiconductors, and polymers.
