METHOD AND APPARATUS FOR MEASURING SEEBECK COEFFICIENT AND/OR THERMAL CONDUCTIVITY OF MEMBRANE SAMPLE

摘要

PROBLEM TO BE SOLVED: To solve the problem, wherein a simple method and apparatus capable of efficiently measuring the Seebeck coefficient and thermal conductivity of a thermoelectric conversion element (membrane), at the same time, have not been available.;SOLUTION: A substrate 2, on which a membrane sample 1 is pasted, is placed on a heater block 1; the pasted side of the membrane sample 1 of the substrate 2 is further covered with a transparent hood 4, and these structures are integrally held in a substantially vertical state, and by carrying out air blowing 5 to the surface of the hood to form a temperature difference between the side surface of the hood (the front surface of the sample) of the membrane sample 1 and the side surface of the substrate (the rear surface of the sample); and the Seebeck coefficient or the thermal conductivity is measured, on the basis of the temperature difference.;COPYRIGHT: (C)2009,JPO&INPIT
