| Popis: | Superconductor-ferroelectric-superconductor (SFS) structures were produced by magnetron sputtering of ceramic YBa2Cu3O7- delta and BaxSr1-xTiO3 targets. Raman spectroscopy was effectively used for characterization of superconducting and ferroelectric films in layered structures. Electrical characteristics, such as the temperature dependence of resistance, current-voltage and capacitance-voltage characteristics were measured. The possibility of applying SFS structures as cryoelectronic capacitors with voltage control is demonstrated. |
