Influence of excitation dragging by phonons on the thermoelectric effect in pure superconductors
Gurevich L. E. , Krylov E. T.
We consider the influence of excitation dragging by phonons on the thermoelectric effect in pure superconductors, when the excitation mean free path is bounded by scattering by phonons. It is shown that the dragging can greatly increase the "thermoelectric angle," by a value up to π. Whereas in superconductors in which the excitations are scattered mainly by impurities the effect decreases with decreasing temperature, in pure superconductors the dragging can lead to an increase of the effect with decreasing temperature if the phonon mean free path continues to increase in this case.
