我们报告了关于清洁和还原的 CrO2(100) 表面的第一原理研究的结果。结果表明,两个表面都保留了半金属性,因为它们有一个共同的特征:表面 Cr 原子也表现得像孤立的离子。因此,CrO2表面的半金属性可以通过基于洪德法则的简单模型来定性地理解。
We report the results of a first principles study on the clean and the reduced CrO2(100) surface. It is shown that both surfaces retain the half-metallicity because they share a common feature: the surface Cr atom also behaves like an isolated ion. Thus, the half-metallicity of the CrO2 surfaces can be qualitatively understood by a simple model based on Hund’s rule.
