Abstract

The adsorption of Mg and Ba on a single domain (SD) Si(001)2 × 1 surface has been studied by using low energy electron diffraction (LEED) and x-ray photoelectron spectroscopy (XPS). SD 2 × 3-Mg and 2 × 2-Mg phases appeared when Mg was deposited on the substrate at 280 and 390°C, respectively. On the other hand, the adsorption of Ba on the substrate at 870°C produced a series of double domain (DD) ordered phases, such as 2 × 3-Ba, mixed, and 2 × 1-Ba, with increasing coverage. Based on our observation of the changes in the intensity ratios of XPS core levels (Mg 1s/ Si 2p and Ba 3d/Si 2p), we suggest that the coverage of the 2 × 3-Mg and -Ba, the 2 × 2-Mg, and 2 × 1-Ba surfaces are 1/3, 1/2, and 1 monolayer (ML), respectively.
