Tunneling potentials associated with thermoelectric quasiparticle transport in superconductors

  • Published:
Journal of Low Temperature Physics Aims and scope Submit manuscript

A superconductor in a thermal gradient assumes a steady state with counterflowing super and normal currents. A quasiparticle transport theory is presented for this current, and the resulting nonequilibrium quasiparticle distribution function is used to discuss NIS tunneling. For zero tunneling current, we derive a bias voltage which is quadratic in ▽ T and which is of roughly the same magnitude as the linear effect recently measured by Falco.
