Fundamental and higher-order harmonic x-ray standing wave measurements were combined to directly measure the lattice positions and thermal vibrational amplitudes of Ga adatoms on the Si(001) surface. In this room temperature study, surface structural parameters such as ad-dimer bond lengths were also determined with much higher accuracy than previous studies.
