Thin Al‐layers were prepared by Knudsen‐type evaporation of Al onto {111} Si in a custom built UHV‐reactor. Epitaxial growth was found on clean substrate surfaces with (7 × 7) reconstruction. In situ RHEED provides the epitaxial relationshipThe epitaxial films show a twelve‐fold symmetry axis according to the combination of the 4‐fold and 3‐fold symmetry of the {001} deposit plane and of the substrate surface, respectively.
