DOIAbstract
The quality of YBa2Cu3O7−δ biepitaxial grain boundary Josephson junctions has been improved and ‘tunnel-like’ characteristics are reproducibly obtained. The consequent low barrier transmission probabilities are 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
