We performed low-temperature scanning tunneling microscopy, low-energy electron diffraction, angle-resolved photoemission spectroscopy, and in situ Raman spectroscopy to investigate the exotic electronic characteristics of the two-dimensional Ag2Ge surface alloy associated with Ge–Ag interactions. The dynamics of Ge insertion into the Ag(111) substrate has been identified, which is distinct due to the metalloid nature of Ge. The ordered structure of the Ag2Ge alloy is determined by the Ag–Ge interaction, which can be controlled by the coverage of Ge atoms on the Ag(111) surface. The linear dispersions of surface states across the Fermi level have been identified in Ag2Ge by angle-resolved photoelectron spectroscopy, which suggests that Ag2Ge could be a potential candidate material for high-performance electronic applications.
