摘要：

Methods for calculating model diffraction profiles of vicinal surfaces and distributions of islands are described. Modeling of rough terrace edges, and of island structures on terraces, has been performed using phenomenological Hamiltonians. The methods are developed for calculating diffraction profiles in all components, s(x), s(z), and s(y), of the momentum transfer. It is shown that the extent of step structure irregularities is related to profile shape. Qualitative comparison with experiment is made based on the observed characterisitcs of terraces obtained from STM and LEED data of vicinal Si(001).
