Reflection high-energy electron-diffraction has been widely used to study surface morphology and crystal growth. Because the technique works well in-situ, it is the technique of choice for studying surface structures that are formed at different temperatures during epitaxial crystal growth. While in the past there have been many RHEED studies, quantitative structural analysis at the atomic level has not been achieved due to the lack of accurate theoretical calculations of RHEED intensity. A specularly reflected RHEED electron at 20,0000 eV in an angular range 0–8° from the surface undergoes the same net momentum transfer as that of a normally incident LEED electron. Thus, it is easy to realize that the RHEED technique has the potential to become as sensitive and versatile a structural tool as LEED spectroscopy [1]. Among difficulties to overcome is the formulation of an accurate and practical method for calculating RHEED rocking-curve intensity spectra. In this paper, we shall discuss key features of such a method and present intensity results on Ag(001) and GaAs(110).
