摘要：

To explore the electrical characteristics of monolithic microwave circuits with integrated high-temperature superconductor and ferroelectric materials, we fabricated a series of coplanar waveguide transmission lines in laser-deposited YBa2Cu3O7-delta and SrTiO3 thin films. We characterized the voltage-tunable two-port microwave response of the transmission lines at cryogenic temperatures using a calibrated network analyzer system, Total phase shifts and phase tuning in these devices increased for increasing ferroelectric film thickness with only moderate increases in transmission loss.
