摘要：

A simplified approach to calculating the two-beam x-ray reflectivity of any planar heterostructure crystal is presented. Darwin's recursion formulas are applied to the individual atomic planes of any layered structure, and the reflectivity is calculated numerically. The results are exact for arbitrary composition profiles and essentially all angles, without requiring crystalline periodicity. This method is equally useful for perfect crystal substrates with submonolayer surface layers, for superlattices, or for arbitrary multilayer structures. © 1995 The American Physical Society.
