• Electron diffraction - Wikipedia

    en.wikipedia.org/wiki/Electron_diffraction Electron diffraction refers to the wave nature of electrons.However, from a technical or practical point of view, it may be regarded as a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon is commonly known as wave–particle duality, which states that a particle of matter (in this case the incident electron) can be ...

    www.britannica.com/science/electron-diffraction Electron diffraction, interference effects owing to the wavelike nature of a beam of electrons when passing near matter. According to the proposal (1924) of the French physicist Louis de Broglie, electrons and other particles have wavelengths that are inversely proportional to their momentum.

    www.merriam-webster.com/dictionary/electron%20diffraction Electron diffraction definition is - an effect due to the wavelike nature of electrons and observed when a narrow beam of them upon passing through a very thin layer of a material (such as a metal crystal) is deflected in particular directions and if allowed to fall on a fluorescent screen produces a pattern of light and dark areas, the pattern formed by these areas being characteristic of the ...

    encyclopedia2.thefreedictionary.com/electron+diffraction Electron diffraction in gases and liquids is similar in principle to that in solids; the differences arise from the lack in gases and liquids of any highly regular arrangement of the component atoms. In gases the low density makes it possible to study diffraction by individual atoms and molecules. The results obtained from monatomic gases ...

    www.sciencedirect.com/topics/chemistry/electron-diffraction Electron diffraction is a powerful tool for materials research ever since the invention of TEM. A popular experimental set up for electron diffraction is the so called selected area diffraction (SAD). Using parallel illumination, the area of interest is selected by placing an aperture in the image plane of the objective lens.

    physics.bu.edu/ulab/modern/Electron_Diffraction.pdf Electron Diffraction Do moving electrons display wave nature? To answer this question you will direct a beam of electrons through a thin layer of carbon and analyze the resulting pattern. Theory Louis de Broglie originated the idea that moving electrons may exhibit both particle and wave nature.

    www.intechopen.com/books/.../electron-diffraction Electron diffraction patterns are used to obtain quantitative data including phase identification, orientation relationship and crystal defects in materials, etc. At first, a general introduction including a geometrical and quantitative approach to electron diffraction from a crystalline specimen, the reciprocal lattice and electron diffraction ...
  • electron diffraction - ETH Z

    www.microscopy.ethz.ch/ED-1.htm Electron diffraction is a collective scattering phenomenon with electrons being (nearly elastically) scattered by atoms in a regular array (crystal). This can be understood in analogy to the Huygens principle for the diffraction of light. The incoming plane electron wave interacts with the atoms, and secondary waves are generated which ...

    instructor.physics.lsa.umich.edu/adv-labs/.../electron_diffraction2.pdf The electron diffraction tube is a small cathode ray tube (CRT) similar to that in a small (old-fashioned) TV set. The electrons pass through a target that consists of graphite, only a few molecular layers thick, vapor-deposited on a micromesh nickel grid. The target is crystalline in tiny regions, so a
