Essential Differences Between ab And c Axis Tunneling And Zero Bias Conductance In The Cuprates
نویسنده
چکیده
The peculiarities in tunneling characteristics have been studied in the light of the controversy between s-wave and d-wave character of High Tc superconductivity. We show that anisotropic s-wave gap has the same low voltage power law conductance and two peak structure in the density of states as d-wave superconductors. The assymetric tunneling conductance and zero bias conductance for the c-axis tunneling is shown to occur because of finite band splitting coming from the interlayer hopping param-

Zero Bias Conductance Peak Enhancement in Bi2Sr2CaCu2O8/Pb Tunneling Junctions
We found strong zero bias conductance peak enhancement in Bi2Sr2CaCu2O8 by tunneling in the ab-plane direction. Our results are consistent with recent studies on Andreev reflection between a d-wave superconductor and normal metal. We have also observed exotic behaviors of the conductance peak if the counter electrode is a conventional superconductor. If these characteristics are better understo...
متن کاملZero-bias anomaly in CrO2 junctions
– CrO2 thin films, with crystallites of several microns size, provide the opportunity for the investigation of the intergrain tunneling between a few crystals separated by a 1–2 nm thick Cr2O3 film. A pronounced zero-bias anomaly of the conductance is found at low temperatures. Combined photoemission and inverse photoemission temperature-dependent studies confirm the occurrence of Coulomb block...
متن کاملNormal-state C-axis Resistivity of the High-tc Cuprate Superconductors
It is shown that a strong intraplanar incoherent scattering can effectively block the interplanar coherent tunneling between the weakly coupled planes of the highly anisotropic but clean (intrinsic) materials such as the optimally doped high-Tc layered cuprate superconductors. The calculated normal-state C-axis resistivity ρc(T ) then follows the metal-like temperature dependence of the ab-plan...
متن کاملPoint Contact Study of the Superconducting Order Parameter in Rusr 2 Gdcu 2 O 8
We have performed a detailed study of the conductance characteristics obtained by point contact junctions realized between a normal Pt/Ir tip and syntered RuSr 2 GdCu 2 O 8 (Ru-1212) samples. Indeed, this compound is subject of great interest due to the coexistence of both magnetic order and bulk superconductivity. In our experiments, the low temperature tunneling spectra reproducibly show a ze...
متن کاملZero-bias peaks in the tunneling conductance of spin-orbit-coupled superconducting wires with and without Majorana end-states.
One of the simplest proposed experimental probes of a Majorana bound state is a quantized (2e(2)/h) value of zero-bias tunneling conductance. When temperature is somewhat larger than the intrinsic width of the Majorana peak, conductance is no longer quantized, but a zero-bias peak can remain. Such a nonquantized zero-bias peak has been recently reported for semiconducting nanowires with proximi...
