Fig. 4: Crystallography and exfoliation of flat GdPtSb membranes.
From: Epitaxy, exfoliation, and strain-induced magnetism in rippled Heusler membranes
a XRD θ–2θ (Cu Kα) scans before exfoliation (black) and after exfoliation (blue). Sapphire substrate reflections are marked by asterisks. In addition to the epitaxial lll-type reflections, a small 004 reflection is observed and marked with a diamond. b Photos of GdPtSb membrane exfoliation from a 1 × 1 cm2 substrate. The left image shows a flat exfoliated membrane bonded to a glass slide. The right image shows the substrate side after exfoliation. In the region that had been covered with graphene (~6 × 6 mm2 square at center), the GdPtSb membrane has been exfoliated to yield a transparent sapphire substrate. In the region not covered by graphene, the GdPtSb film remains adhered to the substrate.
