Abstract
We report direct observations by high-resolution electron microscopy of oxygen desorption from tungsten trioxide. Clear evidence is found for layer epitaxial growth of metallic tungsten with (110)W|(100)WO3 and [001]W and [001]WO3 parallel to the electron beam, consistent with low-energy electron diffraction data on the low-temperature epitaxy of WO3 on W. W[001] was always observed parallel to the electron beam independent of the surface normal. The results suggest that bulk and surface damage, and displacement processes, are similar.
