Abstract

We have calculated the electronic thermal conductivity of a strong-coupling superconductor consisting of free-electron planes stacked up in the z direction with coherent hopping between planes. It is found that planar anisotropy can drastically alter the temperature variation of the thermal conductivity. In our model, the effects are larger for the x-y plane conductivity than they are for the z axis and decrease with coupling strength.
