Abstract

We present a study of the thermoelectric effects in tunnel junctions. In particular we calculate the thermoelectric power coefficient S and the Peltier coefficient P{cyrillic}. For macroscopic junctions we demonstrate the sensitivity of S and P{cyrillic} to the structure of the density of states. For mesoscopic junctions we show that Coulomb effects modify the ordinary Onsager picture and the relation P{cyrillic}=-TS. The coefficients S and P{cyrillic} are found to be very sensitive to the coupling of the junctions to the external world. We comment on the relevance of these effects to scanning tunneling microscope measurements.
