离子晶体中的局部电子结构缺陷通常使用嵌入式簇计算来建模。在本文中,我们描述了如何将量子簇(QC)嵌入点电荷阵列中。具体来说,该方法计算点电荷阵列,在 QC 内部以通常 < 1 μV 的精度再现无限晶体的静电势。 (C) 2000 年由 Elsevier Science B.V. 出版。保留所有权利。
Local electronic structure defects in ionic crystals is commonly modeled using embedded cluster calculations. In this context we describe how to embed the quantum cluster (QC) in an array of point charges. Specifically, the method calculates an array of point charges that reproduces the electrostatic potential of the infinite crystal within an accuracy usually < 1 mu V in the interior of the QC.
