reflection high energy electron diffraction (RHEED)
Any technique which measures the angular intensity distribution of electrons 'reflected' from a crystalline surface under bombardment with high energy electrons near grazing incidence. The @D01711@ pattern provides very surface sensitive information (information depth \(1\ \text{nm}\)) on the atomic arrangement of the top layers of a solid.
