Abstract

Isothermal and quasi-adiabatic Hall and Nernst coefficients were measured on n- and p-type Bi2Te3 over a temperature range 100°K to about 450°K. The current flow was parallel to the cleavage planes, and measurements were made with the magnetic field either parallel or perpendicular to the cleavage planes. The difference between the two Hall coefficients follows the expected variation with temperature. However, the Nernst coefficients do not, and the reason is not known. Results obtained with the magnetic field perpendicular to the cleavage planes have been used to calculate the Ettingshausen coefficient.
