Description
In this study, we investigated the role of oxygen in the faceting of the W(111) surface at temperatures close to T = 20000C. For that purpose, we characterized the W(111) surface before and after the annealing step by low energy electron diffraction (LEED), reflection high energy electron diffraction (RHEED), scanning tunneling microscopy (STM), and Auger electron spectroscopy (AES). It is found that W(111) undergoes a massive reconstruction to form three sided pyramids of nanometer dimensions with mainly (211) planes as facet sides. Interestingly, the facetted W(111) surface is deprived from oxygen. We then show how the facetted W(111) surface can be used as a template to deposit platinum by molecular beam epitaxy.
