Pma. Cook et al., PHASE COHERENT TRANSPORT IN HYBRID SUPERCONDUCTING STRUCTURES - THE CASE OF D-WAVE SUPERCONDUCTORS, Czechoslovak journal of Physics, 46, 1996, pp. 1045-1046
We examine tile effect of d-wave symmetry on zero bias anomalies in no
rmal-superconducting tunnel junctions. In the presence of d-wave pairi
ng, zero-bias anomalies are suppressed compared with the s-wave case.
