摘要：

In this study we revisit the properties of the ("8.88 x 8.88")R30 degrees 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 x 8.88)R30 degrees surface, which presents two surface bands, with having linear dispersion at the Fermi level.
