Analysis of reflection high energy electron diffraction azimuthal plots (original) (raw)
ADS
Abstract
Reflection high energy electron diffraction data collected in the form of an azimuthal plot are analyzed theoretically for the first time. Experimental results for Si(111) at a glancing angle satisfying a Bragg condition are taken from the literature. Calculations are carried out within a multiple scattering approach. Excellent agreement between experimental and theoretical results is achieved. A simple qualitative explanation of the shape of the azimuthal plot analyzed is also presented.
