On dissipation mechanism in the intrinsic Josephson effect in layered superconductors with coherent interlayer tunnelling
S. N. Artemenko
Abstract
The mechanism of conductivityin the regime of the intrinsic Josephson effect is studied in layered superconductors with singlet d-wave pairing. The cases of coherent and incoherent interlayer tunneling of electrons are considered. The theory with coherent tunnelling describes main qualitative features of the effect observed in highly anisotropic high-Tc superconductors at voltages smaller than the amplitude of the superconducting gap, the mechanism of resistivity being related to the excitations of quasiparticles via the d-wave gap. Interaction of the Josephson junctions formed by the superconducting layers due to the charging effects is shown to be small.
