Description
The differential conductivities of Bi2Sr2CaCu2O8+x/Au and YBa2Cu3O7-δ/Au point contacts were measured. The superconducting order parameter Δ and the Fermi velocity vF of both superconductors were determined making use of the modified Blonder-Tinkham-Klapwijk theory. The coherence length and penetration depth of Bi2Sr2CaCu2O8+x and YBa2Cu3O7-δ were calculated from Δ and vF, by applying a weak-coupling theory of superconductors with anisotropic single-particle dispersion and order parameter. Our results are compared to other experimental data. (orig.)
