Pb/Si (111) surface superstructures have been studied using reflection high energy electron diffraction (RHEED) and molecular beam deposition techniques. The dependences of Pb/Si (111) surface structures on the Pb coverage and on the substrate temperature were elucidated on the basis of the RHEED observation in the coverage range from 0ML to 2ML and in the temperature range from 30°C to 500°C.
In addition, we have measured changes in the RHEED intensities during Pb deposition. The results of the RHEED intensity measurements show that the saturation coverage for √3×√3 (α) and √3×√3 (β) superstructures are 4/3ML and 1/3ML, respectively.
