• 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.
  • Electron Diffraction - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/chemistry/electron-diffraction Electron diffraction patterns are mainly contributed by elastic scattering. In an electron microscope, the diffraction pattern appears either on a fluorescent screen or is recorded on a photographic film or detected by a sensor such as a CCD (charge-coupled device) camera. From the diffraction pattern, the arrangement of the atoms in a material ...
  • Low-energy electron diffraction - Wikipedia

    en.wikipedia.org/wiki/Low-energy_electron_diffraction Low-energy electron diffraction (LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low energy electrons (20–200 eV) and observation of diffracted electrons as spots on a fluorescent screen.. LEED may be used in one of two ways: Qualitatively, where the diffraction pattern is recorded and analysis of ...

    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.
