“…A clear hysteresis and voltage jump were observed. The magnitude of the first voltage jump was approximately 20mV, in accordance with one Josephson junction [10]. The critical current density JC was estimated to be 1400 A/cm 2 .…”

A novel phenomenological approach to the analysis of the conductivities of incoherent layered crystals is presented. It is based on the fundamental relationship between the resistive anisotropy σ ab /σc and the ratio of the phase coherence lengths in the respective directions. We explore the model-independent consequences of a general assumption that the out-of-plane phase coherence length of single electrons is a short fixed distance of the order of interlayer spacing. Several topics are discussed: application of the scaling theory, magnetoresistivity, the effects of substitutions and the intermediate regime of conduction when both coherence lengths change with temperature, but at different rate.

“…This is due to the π phase difference between adjacent lobes of the d-wave gap parameter. The other extreme of purely coherent tunneling between d-wave superconductors would provide the maximum value of I C in an SIS junction but it leads to peculiar single-particle tunneling conductances, including linear dI/dV at subgap bias voltages [7,8] that are not observed.…”

The c-axis current-voltage I (V ) characteristics have been obtained on a set of mesas of varying height sculpted on Bi 2 Sr 2 CaCu 2 O 8 + δ (Bi2212) crystals intercalated with HgB 2 . The intercalation, along with the small number of junctions in the mesa, N = 6-30, minimizes the degree of self-heating, leading to a consistent Josephson critical current, I C , among junctions in the mesa. The Bi2212 crystals with a bulk T C = 74 K are overdoped and display negligible pseudogap effects allowing an accurate measure of the normal state resistance, R N . These properties make the mesas nearly ideal for the determination of the Josephson I C R N product. We find I C R N values consistently ∼30% of the quasiparticle gap parameter, /e, which was measured independently using a mechanical contact, break junction technique. The latter was necessitated by higher bias heating effects in the mesas which prevented direct measurements of the superconducting gap. These values are among the highest reported and may represent the maximum intrinsic value for I C R N . The results indicate that the c-axis transport is a mixture of coherent and incoherent tunneling.
