X-ray standing waves generated by dynamical Bragg diffraction were used as an element-specific structural probe for investigating Sb adsorption on Si(0 0 1). These high-resolution measurements of the Si(0 0 1)/Sb-(1 × 2) surface reveal important quantitative structural information regarding the dimerized surface structures, such as Sb ad-dimer height, Sb dimer bond length, Sb thermal vibration amplitude, and inward contraction of the Si surface.
