Reflection high-energy electron diffraction (RHEED) is a technique used to characterize the surface of crystalline materials. ... Transmission electron microscopy, another common electron diffraction method samples the bulk of the sample due to the geometry of the system.
What is difference between low and high energy electron diffraction techniques?
Reflection high-energy electron diffraction (RHEED) is a standard diffraction method in surface science, but contrary to low-energy electron diffraction (LEED) the analysis of morphology and defect structure is not as reliable due to inelastic scattering and a more complicated scattering geometry.
What is RHEED used for?
RHEED is an extremely popular technique for monitoring the growth of thin films. In particular, RHEED is well suited for use with molecular beam epitaxy (MBE), a process used to form high quality, ultrapure thin films under ultrahigh vacuum growth conditions.
