Abstract

We report the synthesis of millimeter-sized freestanding single-crystal YBa₂Cu₃O_7-x heterostructure membranes with nanoscale thickness. On a SrTiO₃ substrate, a heteroepitaxial water-soluble sacrificial layer of Sr₃Al₂O₆ followed by an encapsulated YBa₂Cu₃O_7-x film is grown by pulsed laser deposition. A freestanding YBa₂Cu₃O_7-x heterostructure membrane is obtained by etching the sacrificial layer. Its high crystalline quality is demonstrated via x-ray diffraction, electrical measurements, and scanning transmission electron microscopy.
