TI - Graphoepitaxial high-T$_{c}$ SQUIDS JO - Journal of physics / Conference Series VL - 507 SN - 1742-6588 CY - Bristol PB - IOP Publ. M1 - FZJ-2014-03348 SP - 042009 PY - 2014 AB - The fabrication process and physical properties of graphoepitaxially engineered high-Tc direct current superconducting quantum interferometer devices (DC SQUIDs) are studied. Double buffer layers, each comprising a graphoepitaxial seed layer of YBa2Cu3O7−x and an epitaxial blocking layer of SrTiO3, were deposited over textured step edges on (001) surfaces of MgO substrates. Scanning electron microscopy and high-resolution transmission electron microscopy were used to investigate the microstructural properties of DC SQUIDs with graphoepitaxial Josephson junctions. Both direct coupled and inductively coupled high-Tc DC SQUIDs with graphoepitaxial step edge junctions and flux transformers were studied.
