铂低指数表面的电子能带结构:{ \it ab initio}和紧束缚研究。II

Electronic band structure of platinum low--index surfaces: an {\it ab initio} and tight--binding study. II

H. J. Herrera-Suarez, A. Rubio-Ponce, D. Olguin

摘要:

作为前一篇论文的第二部分,本文用密度泛函理论和经验紧束缚方法计算了Pt(100)和Pt(110)表面的电子能带结构。详细讨论了表面态和共振态。计算结果表明,理想Pt(100)表面的表面态和共振态与已有的实验数据符合得很好。对于Pt(110),一些表面和共振态是表面低对称度的特征,并且被识别为与表面重构效应无关。与前一篇论文一样,密度泛函计算使用全势线性缀加平面波方法进行,经验计算使用紧束缚方法和表面格林函数匹配方法进行。

英文摘要:

As a second part of a previous paper, here the calculated electronic band structure of ideal Pt(100) and Pt(110) surfaces, studied using density functional theory and the empirical tight-binding method, is presented. A detailed discussion of the surface- and resonance--states is given. It is shown that the calculated surface- and resonance--states of ideal Pt(100) surfaces agree very well with the available experimental data. For Pt(110), some of the surface- and resonance-states are characteristic of the low degree of symmetry of the surface and are identified as being independent of surface reconstruction effects. As in the previous paper, the density functional calculations were performed using the full potential linearized augmented plane wave method, and the empirical calculations were performed using the tight-binding method and Surface Green's Function Matching Method.
