Abstract
The properties of LiB3O5 (LBO) surfaces have been studied with reflection high energy electron diffraction (RHEED) and Xray photoelectron spectroscopy (XPS). The superstructure ordering with the relations a=4a0, b=2b0 and c=2c0, where a0, b0 and c0 are the LBO cell parameters, has been detected by RHEED analysis. Depth profiling by XPS shows that the thickness of the top surface layer contaminated by carbon is ~20 Å. Electronic parameters of LBO have been defined for the surface cleaned by ion beam sputtering. The ratio of original elements at the surface is in close relation with the formal composition of LBO.
