The reconstruction of a W(100) surface covered with half a monolayer of oxygen was investigated by means of work function measurements, low-energy electron diffraction, Auger spectroscopy, and electron stimulated desorption. Structural properties of the reconstructed surface were presented for a number of stages during the reconstruction process. The once reconstructed surface was shown to undergo a reversible phase transition at elevated temperatures. A model for this transition was proposed.
