Abstract

The surface spin-polarized states in the electronic structure of Pt(111) and graphene/Pt(111) have been studied in detail using angle-resolved photoelectron spectroscopy and density functional theory calculations. The results obtained show the presence of cone-shaped surface states near the Fermi level in the vicinity of the \(\bar {M}\) point of the surface Brillouin zone of platinum for both systems. Theoretical calculations confirm that these states are spin-polarized surface states of Pt(111) single crystal.

铂(111)和石墨烯/铂(111)电子结构中的自旋极化态

摘要利用角度分辨光电子能谱和密度泛函理论计算详细研究了铂(111)和石墨烯/铂(111)电子结构中的表面自旋极化态。研究结果表明，在这两种体系的铂表面布里渊区的（\bar {M}\）点附近的费米级附近存在锥形表面态。理论计算证实这些态是铂(111)单晶的自旋极化表面态。
