Critical currents along the c-axis have been studied in single crystalline Bi2Sr2CaCu208+ 8 in magnetic fields. It is ohserved that the current-voltage relation has a sudden jump with a characteristic hysteresis, reminiscent of the typical Josephson junction character. The maximum critical current d
Josephson tunneling I-V characteristics have been observed in break j unctions of oxygen-annealed Bi2Sr2CaCu2Os (Bi-2212 ) single crystals, with foR. ~ 21.3 mV, and with a sharp quasipartiele edge at 2zt ~ 2 × 20 mV. This demonstrates that low values of the IoR. product, thus far as observed in HTS
We present a phenomenological model for the electrical transport in double-layered cuprates, based on the existence of two energy barriers along the c-axis. The model is applied to measurements of the dc resistivity in Bi 2 Sr 2 CaCu 2 O 8+d single crystals. We find that the model gives a comprehens
