| Research Abstract |
Initial stages of reactive deposition epitaxy of FeSi2 on Si(001)were observed by in situ X-ray diffraction. At 450℃, nitially nano-crystallites of α-FeSi2 high-temperature phase are formed. With increasing thickness of the deposited Fe, the α-FeSi2 crystallites gradually disappear and β-FeSi2, which is the stable phase at the growth temperature, supersedes them completely. The α-axis of the β-FeSi2 film aligns to the Si[001] axis during annealing up to 900℃.
