Thermoelectric power and nonstationary Josephson effect in S-N-S structures
Aronov A.G., Gal'perin Yu. M.
It is shown that if a temperature difference is produced on an S-N-S structure, then an ac component of current appears in a circuit containing this structure; its frequency is proportional to the absolute differential thermoelectric power of the normal metal and to the temperature difference on the junction.
