Initial stages of Zr-Fe-Si alloy formation on Zr(0001) surface

Popis výsledku v původním jazyce

We studied initial stages of Fe and Si atoms interaction with the Zr(0001) surface. Fe and Si were deposited in situ on the clean Zr surface up to coverage of one monolayer. Chemical state of Zr as a function of annealing temperature and the surface composition was investigated. Characteristic (1x1) LEED (Low Energy Electron Diffraction) pattern of the clean Zr surface becomes significantly modified when Fe and Si are deposited and annealed at 400 degrees C. The arrangement of new spots of the pattern corresponds to the (2 root 3 x2 root 3)R30 degrees structure, stable up to annealing at 750 degrees C. Changes in the electronic structure were identified from the images of equienergy cuts of the k-space covering the entire Brillouin zone. The results imply that hydrogen, typically present in the clean surface, was eliminated either by annealing or upon the deposition of Fe and Si.
