Abstract

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.
