Flavours of intrinsic d-wave induced effects in O_(7-δ) grain boundary Josephson junctions

摘要

The quality of YBa_2Cu_3O_(7-δ) biepitaxial grain boundary Josephson junctions has been improved and "tunnel-like" characteristics are reproducibly obtained. The consequent low barrier transmission probabilities is apparently favourable to isolate intrinsic d-wave induced effects. Extrinsic and intrinsic d-wave effects are discussed within the framework of novel designs for π-circuitry and qubits.
