Abstract

The simulation of EXAFS spectra of thin films via ab initio methods is discussed. The procedure for producing the spectra is presented as well as an application to a two-dimensional material (WSe) where the effectiveness of this method in reproducing the spectrum and the linear dichroic response is shown. A series of further examples in which the method has been employed for the structural determination of materials are given.

摘要

讨论了通过从头算方法对薄膜的扩展X射线吸收精细结构(EXAFS)光谱进行模拟。介绍了生成光谱的过程,以及该方法在二维材料(WSe)中的应用,展示了此方法在再现光谱和线性二向色性响应方面的有效性。还给出了一系列该方法用于材料结构测定的进一步示例。
