Abstract
The oxidation of the W(1Â 0Â 0) surface at elevated temperatures has been studied using room temperature STM and LEED. High exposure of the clean surface to O2 at 1500Â K followed by flash-annealing to 2300Â K in UHV results in the formation of a novel p(3Â ÃÂ 1) reconstruction, which is imaged by STM as a missing-row structure on the surface. Upon further annealing in UHV, this surface develops a floreted LEED pattern characteristic of twinned microdomains of monoclinic WOx, while maintaining the p(3Â ÃÂ 1) missing-row structure. Atomically resolved STM images of this surface show a complex domain structure with single and double Wã0Â 1Â 0ã rows coexisting on the surface in different domains.
