| 中文摘要 | Investigation by transmission electron microscopy and high-resolution transmission electron microscopy was carried out on YBa2Cu3O7-delta thin films grown on vicinal SrTiO3 substrates by pulsed laser deposition. The c-axis YBa2Cu3O7-delta films grown on 1degrees-3degrees miscut substrates displayed a step-flow crossover to three-dimensional island growths, and on 6degrees-15degrees miscut substrates displayed a complete step-flow growth. Perfect heteroepitaxial growth of Ba0.1Sr0.9TiO3/YBa2Cu3O7-delta (BST/YBCO) on 1.2degrees miscut (001) LaAlO3, has been achieved by modification of the deposition conditions. The capacitance-voltage properties of a BST/YBCO capacitor were measured under a dc bias of +/-30 V and 1 MHz frequency at 77 K, and the dielectric constant, tunability and figure of merit were found to be 1200, 60% and 133, respectively. These values show that the BST films have potential application at liquid nitrogen temperature in electrically tunable microwave devices. |
