Electron energy loss spectroscopy — In electron energy loss spectroscopy (EELS) a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their… … Wikipedia
Energy filtered transmission electron microscopy — (EFTEM) is a technique used in Transmission electron microscopy, in which only electrons of particular kinetic energies are used to form the image or diffraction pattern. The technique can be used to aid chemical analysis of the sample in… … Wikipedia
Electron microprobe — An electron microprobe (EMP), also known as an electron probe microanalyser (EPMA) is an analytical tool used to non destructively determine the chemical composition of small volumes of solid materials. It works similarly to a scanning electron… … Wikipedia
Electron spectrometer — In an Electron spectrometer, an incoming beam of electrons is bent with electric or magnetic fields. As higher energy electrons will be bent less by the beam, this produces a spatially distributed range of energies. Electron spectrometers are… … Wikipedia
Scanning transmission electron microscopy — A scanning transmission electron microscope (STEM) is a type of transmission electron microscope. With it, the electrons pass through the specimen, but, as in scanning electron microscopy, the electron optics focus the beam into a narrow spot… … Wikipedia
Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… … Wikipedia
