An inhomogeneous Josephson junction array model in HTSC granular bridges

초록

Experimental and theoretical studies are reported of the electrodynamic behaviours, such as current-voltage characteristics (IVCs), microwave self-radiations and dynamic resistances, dV/dl, of granular high-T-c superconducting (HTSC) YBa2Cu3Oy (YBCO) and Bi2Sr2CaCU2Oy (BSCCO) film bridges. We show that the granular structure of bridges can be understood as series-connected independent and inhomogeneous resistively shunted junction (RSJ) arrays.
