Experimental study of the transverse Ettingshausen-Nernst effect and thermoelectric power in the presence of a large temperature gradient
1998
The transverse Ettingshausen-Nernst effect and the thermoelectric power of compensated germanium with electron density n=2×1011 cm−3 are investigated as a function of the temperature gradient in the range 2−1.5×103 K·cm−1 at average temperature 350 K. It is shown that the mechanism of charge-carrier scattering does not depend on the temperature gradient, while the Benedick thermoelectric power is due to heating of the current carriers by the heat field.
