Surface reconstructions of a submonolayer Sb/Si(111) system were investigated by low-energy electron diffraction and X-ray photoelectron spectroscopy. It has been found that the surface superstructures of diffuse 2Ö2 (or three-domain 2Ö1), √3Ö√3, 5√3Ö5√3 and 7√3Ö7√3 are formed for the Sb coverages around one monolayer.
