Essential Differences between $ab$ and $c$ Axis Tunneling and Zero Bias Conductance in the Cuprates

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/27133The peculiarities in tunneling characteristics have been studied in the light of the controversy between s-wave and d-wave character of High $T_c$ 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 asymmetric 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 parameter.revtex version 3.0, 13 pages 4 figures available on request from sreeram@iopb.ernet.in - IP/BBSR/94-29Condensed MatterEssential Differences between $ab$ and $c$ Axis Tunneling and Zero Bias Conductance in the Cupratestext
