- Аннотация: Dielectric properties of both Nd1.9Ba1.1Cu3O7+delta (NBCO-213) and Pr1.14Ba1.86Cu3O7-delta (Pr-rich PBCO) single crystals have been examined at low temperature. These materials have good lattice matching to high-Tc superconductors (HTS), but they are conductive at room temperature. Below 80K, they are insulators with low dielectric constants, epsilon (r) below 25, and low dielectric loss tan delta below 0.1 at 100 kHz, The value of epsilon (r) is suitable for insulators in integrated circuits using strip line widths of 10 mum order, providing short delay time, no excitation of surfacewave, and low radiation loss. The value of tan delta is comparable to loss of superconducting surface resistance above 100 GHz. These results indicate the applicability for the insulator layers in multilayer superconducting electronic devices such as Single Flux Quantum (SFQ) circuits operated at high speed.
