Interlayer transport in the highly anisotropic misfit-layer superconductor(LaSe)(1.14)(NbSe2)

The interlayer transport in a two-dimensional superconductor can reveal a p eak in the temperature as well as the magnetic field dependence of the resi stivity near the superconducting transition. The experiment was performed o n the highly anisotropic misfit-layer superconductor (LaSe)(1.14)(NbSe2) wi th T-c of 1.2 K. The effect is interpreted within the tunneling mechanism o f the charge transport across the Josephson-coupled layers via two parallel channels-the quasiparticles and the Cooper pairs. Similar behavior can be found in the high-T-c cuprates but there it is inevitably interfering with the anomalous normal state. The upper critical magnetic field can be obtain ed from the interlayer tunneling conductance.
