Measurement Method: Thermopower method
"The thermopower was measured by a steady-state method employing a differential Chromel-Constantan thermocouple and a small heater, glued to the specimen with varnish. Seebeck probes were calibrated Cu wires, silver painted to fired-on silver-paint pads. The temperature gradient during measurement was typically 0.5-2.0 K/mm. Linearity in the V(ΔT) response was confirmed by varying the heater power. The uncertainty in the measurements is ±0.1 µV/K."
