c-Axis Twist Bi2Sr2CaCu2O(8+delta) Josephson Junctions: A New Phase-Sensitive Test of Order Parmaeter Symmetry

R. A. Klemm, C. T. Rieck, K. Scharnberg

Li et al. found that the critical current density JcJ across atomically clean c-axis twist junctions of Bi2Sr2CaCu2O(8+x) is the same as that of the constituent single crystal, JcS…
