In the here presented research we report on the synthesis and structural investigation of sub-monolayers antimony on Ag(110). Since the structural configuration of 2D-materials has major influence on the electronic properties of the material, we focus on the analysis of the Sb/Ag interface.

After several cleaning cycles in UHV, antimony is evaporated by a Kudsen cell to deposit different layer thicknesses on the Ag(110) surface. Subsequently the sample is heated and investigated. Low-energy electron diffraction (LEED) and photoelectron spectroscopy (XPS) are used for the structural and chemical investigation of the Sb phases on Ag(110). Our results indicate a strong correlation between the layer thickness and the structural and chemical configuration of the Sb phases, similar to our already published results of germanium on Ag(110) [1].
