Directional Tunneling and Andreev Reflection onYBa2Cu3O7−δSingle Crystals: Predominance ofd-Wave Pairing Symmetry Verified with the Generalized Blonder, Tinkham, and Klapwijk Theory
Abstract
We report directional tunneling and point-contact spectroscopy measurements on the ${100}$, ${110}$, and ${001}$ faces of ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ single crystals at 4.2 K. The conductance spectra show fully developed quasiparticle tunneling, Andreev reflection, and zero-bias peak characteristics, depending systematically on the junction orientation and impedance. Quantitative spectral analysis using the generalized formalism of Blonder, Tinkham, and Klapwijk (BTK) indicates a predominantly ${d}_{{x}^{2}{\ensuremath{-}y}^{2}}$ pairing symmetry, with less than 5% $s$-wave component in either the $d+s$ or $d+is$ scenario.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
