Fe(100) homoepitaxy studied by grazing scattering of fast ions

Spin polarization, structure and chemical composition of the Rh/Fe(100) interface

“…A clearly different behavior is described for the growth at room temperature [42]. The decrease of the specular intensity to approximately 10% of the first and the following oscillation minima implies a substantially larger island density in comparison to growth at 550 K. The higher island density and the enhanced decrease of the oscillation amplitude point to growth of more than one layer.…”

“…2), we compare with the homoepitaxial system Fe on Fe(1 0 0) [42]. It was shown that at a substrate temperature of 550 K an almost perfect layer-by-layer growth over many layers was observed.…”

“…[43][44][45][46], the oscillation maxima correspond to almost completely closed layers of the adsorbed atoms. The decrease of the specular intensity at the oscillation maxima for growth at 550 K was interpreted in [42] as an increasing roughness of the film. This roughness could be smoothed by subsequent annealing and resulted to the specular intensity for the clean substrate surface.…”
