摘要：

Several ordered structures due to Sr adsorption have been observed on the Si(100) surface by low-energy electron diffraction: (1) a (2×3) phase, (2) a (1×2) phase, (3) a compressed (1×5) phase, and (4) a (1×3) phase. The relationship between the ordered structures has been investigated as a function of Sr coverage and substrate annealing temperature. The data suggest that the Sr atoms form atomic chains on the surface, with spacing between the chains decreasing as Sr coverage increases. © 1990 The American Physical Society.
