The impact of compositional disorder on physical properties is a subject of prime focus in many materials systems. In this paper, we report photoemission measurements of Mo_1−x Re _x (110)-(1נ1)H alloy surfaces to probe the relationship between the surface Fermi contours and giant Kohn anomalies observed in the surface phonon dispersion relations. Our measured nesting vectors precisely predict the composition dependence of the anomalous wave vectors.

无规合金表面的表面费米轮廓和声子异常

成分无序对物理特性的影响是许多材料系统的主要关注点。在本文中，我们报告了 Mo _{1− x} Re _x (110)-(1נ1)H 合金表面的光电发射测量，以探讨表面费米轮廓与在表面声子色散关系中观察到的巨大 Kohn 异常之间的关系。我们测量的嵌套向量精确地预测了异常波向量的组成依赖性。
