We show that the zero-bias conductance peak observed in tunnel and point junctions of cuprates can be a consequence of "unitary" elastic scattering of the carriers by non-magnetic impurities in the vicinity of the junction interface and d-wave symmetry of the order parameter.

The influence of (non-magnetic and magnetic) impurities on the transition temperature of a d-wave superconductor is studied anew within the framework of BCS theory. Pairing interaction decreases linearly with the impurity concentration. Accordingly T c suppression is proportional to the (potential or exchange) scattering rate, 1/τ, due to impurities. The initial slope versus 1/τ is found to depend on the superconductor contrary to Abrikosov–Gor'kov type theory. Near the critical impurity concentration T c drops abruptly to zero. Because the potential scattering rate is generally much larger than the exchange scattering rate, magnetic impurities will also act as non-magnetic impurities as far as the T c decrease is concerned. The implication for the impurity doping effect in high T c superconductors is also discussed.
