In this study we revisit the properties of the (8.88×8.88)R30 surface reconstruction obtained by evaporation of Cu on Ge(111), motivated by the predictions of Dirac nodal lines in two-dimensional Cu2Ge monolayer. After providing an updated version of the band structure of Ge(111) by angle-resolved photoemission (ARPES), we present the band structure of the Cu/Ge(111)(8.88×8.88)R30 surface, which presents two surface bands, with having linear dispersion at the Fermi level.

Cu 在 Ge(111) 上不相称的 (8.88×8.88) 不相称的表面重建的角度分辨光电子能谱



在这项研究中,我们重新审视了通过在 Ge(111) 上蒸发 Cu 获得的 (“8.88×8.88”)R30∘ 表面重建的性质,其动机是二维 Cu2Ge 单层中狄拉克节点线的预测。在通过角度分辨光发射 (ARPES) 提供了 Ge(111) 能带结构的更新版本之后,我们提出了 Cu/Ge(111)−(8.88×8.88)R30∘ 表面的能带结构,它呈现两个表面能带,在费米能级具有线性色散。
