Crossover from Thermal Activation to Quantum Interlayer Transport at the Superconducting Transition Temperature of Bi-2212

S. O. Katterwe, A. Rydh, V. M. Krasnov

We perform a detailed study of temperature, bias and doping dependance of interlayer transport in the layered high temperature superconductor Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$. We obse…
