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.

By the advanced preparation technology of thin film, such as terminate oxide substrates at well-defined ionic planes, pulsed-laser deposition (PLD) and molecular-beam epitaxy (MBE), and high-pressure reflection high-energy electron diffraction, many new physical phenomena have been discovered in oxide interfaces [14, 15].
