high-energy electron diffraction

[′hī ‚en·ər·jē i′lek‚trȧn di‚frak·shən]
(physics)
The diffraction of electrons with high energies, usually in the range of 30,000-70,000 electronvolts, mainly to study the structure of atoms and molecules in gases and liquids. Abbreviated HEED.

Tenders are invited for Reflection High-Energy Electron Diffraction (RHEED) System (UW-MAD)
A scanning reflection high-energy electron diffraction (RHEED) system is typically used to perform in situ monitoring of the layer-by-layer epitaxy.
Covering electron diffraction, photoemission, and alternative techniques, they look at reflection high-energy electron diffraction, inelastic scattering, ultraviolet photoemission spectroscopy, X-ray photoelectron spectroscopy, in situ spectroscopic ellipsometry, ion-beam surface characterization of thin multicomponent films, spectroscopies combined with reflection high-energy electron diffraction, deposition vapor monitoring, and real-time studies of epitaxial film growth using surface X-ray diffraction.
In the early 1970s his group studied the corrosion and oxidation of nickel --thin oxide film formation using the unique combination of reflection high-energy electron diffraction and X-ray emission analysis, high-temperature oxidation, and the formation and breakdown of films in aqueous environments.
