Abstract
Tunneling spectra of high temperature superconductor(HTS)/metal contac t junctions exhibiting some anomalous structures are presented and ana lyzed. Quasi-linear conductance background is related to the carrier t ransport through the degraded surface layer, not to the intrinsic prop erties of the cuprates. On contrary, zero-bias conductance peaks can b e explained as a result of d-wave symmetry in the pair potential of hi gh-Tc superconductors.
