Abstract
A new two-dimensional Bloch-wave method is developed for dynamical ref lection high-energy electron diffraction (RHEED) calculations. In this two-dimensional Bloch-wave analysis, the traverse energy and the wave field for each Bloch wave are calculated by a step-by-step R-matrix m ethod. The accuracy of the method is critically examined in comparison with Ichimiya's method on the experimental rocking curve of an Si(001 )-2 x 1 surface. It is demonstrated that two-dimensional Bloch-wave an alysis can be used to elucidate the mechanism causing the peaks in roc king curves.
