Research Abstract

Generation of electric power by the Nernst effect is a new application of a semiconductor. A key point of this new proposal is to find materials with a good figure of merit of the Nernst effect, which is called a Nernst element. We propose InSb as a candidate for the Nernst element, because an electron mobility of InSb is very high at room temperature.. It will be used in a strong magnetic field at high temperatures. The efficiency of this energy conversion depends on transport properties of the Nernst element. Unfortunately we have few data of transport coefficients in such conditions. First we developed the diagnostic system in order to measure transport coefficients (Nernst coefficient, thermoelectric coefficient, Hall coefficient and resistivity) of the Nernst element. From these measurement, we suggest that transport coefficients depend on a shape of a sample. (It is known qualitatively that the resistivity depends on the shape.) Data of the measurement include the shape effect. It is necessary to remove the shape effect from data in order to compare them with calculation by the Boltzmann equation. Next step we analyze the shape effect quantitatively by numerical calculations.
