The surface phase diagram of S/Ni(111) in the temperature range from room temperature to 900 K has been established by reflection high-energy electron diffraction observations in consultation with previously reported data. The temperature dependence of surface diffusion coefficient of sulfur in a p(1 × 1) phase was measured with micro probe Auger electron microscopy from 513 to 597 K. The diffusion coefficient in the p(1 × 1) phase in the coverage region from 0.05 to 0.10 ML is expressed as: D (cm2 s-1) = 2 × 103 exp[-1.1 ± 0.1 (eV)/kBT].
