Abstract

X-ray standing wave measurements, along with local-density molecular cluster calculations, were used to determine the surface structure of the low-coverage Bi/Si(001) surface. The 2×2 Bi phase, predicted by theory to be the stable low-coverage structure, was found experimentally to be a metastable phase and was observed to have a thermally activated irreversible phase transition to the stable 1×2 phase. These measurements represent another approach for investigating the kinetics of surface reactions.
