The structure of the Na/Ge(111) surface has been studied using scanning tunneling microscopy. Na atoms adsorbed preferentially on the domain boundaries and defect sites. At the increased coverage, Na atoms did not form an ordered structure. When the Na-adsorbed surface was annealed, the surface reconstructed to the 3x1 structure. The atomic arrangement of the 3x1 surface was similar to that of the Na/Si(111)3x1 surface.
