26 May 1997 | Journal: | Phys. Rev. Lett. 79, 281 (1997) | Subject: | Superconductivity | cond-mat.supr-con | Affiliation: | Northwestern University), D. Rainer (Universität Bayreuth) and J. A. Sauls (Northwestern University | Abstract: | Theoretical results for the ab-plane tunneling conductance in the d-wave model for high Tc superconductors are presented. The d-wave model predicts surface bound states below the maximum gap. A sub-dominant order parameter, stabilized by the surface, leads to a splitting of the zero-bias conductance peak (ZBCP) in zero external field and to spontaneous surface currents. In a magnetic field screening currents shift the quasiparticle bound state spectrum and lead to a voltage splitting of the ZBCP that is linear in H at low fields, and saturates at a pairbreaking critical field of order 3 Tesla. Comparisons with recent experimental results on Cu/YBCO junctions are presented. | Source: | arXiv, cond-mat/9705260 | Services: | Forum | Review | PDF | Favorites |
