| Popis: | An antimony-doped germanium single crystal was grown by the Axial Heat Processing (AHP) method from the melt to study the influence of facets on the morphological stability of a solid/liquid interface. It is shown that the faceted portion of the interface remains more stable than the non-faceted portion. In addition, instability of the faceted region occurs at a higher solute concentration with larger cell spacing. A mathematical model, accounting for the presence of facet, predicted the solute profile and morphological features of the grown crystal are in good agreement with the experimental data. |
