Measurement Method: Thermopower method
"The thermoelectric power of the samples has been measured using a differential technique where a temperature gradient is created across the sample and the voltage developed...between the hot and cold ends of the thermocouple formed by the sample and Cu wires is measured. In our apparatus we have used two heaters (one at the top and the other at the bottom of the sample) so that either end of the sample may be heated with respect to the other. The temperature difference ΔT between two ends of the sample was kept in the range (of about) ±0.5 K throughout the measured temperature range (77-300 K). The temperature and temperature difference across the sample were measured with Chromel-Alumel thermocouples."
