Surface Structural Determination Using RHEED
There are many reasons why RHEED is attractive as a technique for surface structural determination. Experimentally, RHEED pictures are clearly very sensitive to changes in the surface [1,2,3] and high energy electrons have already proved to be a valuable tool for structural determination in electron microscopy . Theoretically, the reduction in scattering cross sections at higher energies and the easier prediction of the electron scattering potential suggest that calculations of RHEED intensities should be both easier and faster than equivalent calculations at lower electron energies . This brief review will discuss the general theoretical problems raised by attempts to determine structures by RHEED and consider some of the calculations which have been done in recent years.
