Analysis of thermoelectric measurement

Measure seebeck coefficient, electric resistance and thermal conductivity in order to get performance index of a material itself.

Measure seebeck coefficient

Heat both ends of a sample by a heater to make temperature difference of up to 50℃ between the both ends, and measure temperature difference and electromotive force by probe thermocouples pressed on the both ends of the sample.

Electric resistance・Seebeck coefficient
