    Abstract

    The surface phase diagram of S/Ni(1 0 0) in a temperature region from room temperature to 1100 K has been examined by reflection high energy electron diffraction observation, and the temperature and sulfur coverage regions of the p(1×1) phase have been determined. The temperature dependence of surface diffusion coefficient of sulfur in the p(1×1) phase has been measured with micro-probe Auger electron spectroscopy in a temperature region from 820 to 900 K and in a sulfur coverage region from 0.03 to 0.07 ML. The obtained diffusion coefficient in the p(1×1) phase is expressed as D (cm2/s) = 1.0×10-2 exp(-1.0±0.1 (eV)/kBT).
