Combined Seebeck Coefficients And Conductivity Measurements

A powerful possibility lies in the combination of Seebeck coefficient and conductivity measurements. Most typically this involves utilization of the geometry of the bar sample to make true four-point measurements.

The sample is prepared as described for Seebeck measurements, but with two voltage probes at for instance 1/3 and 2/3 length of the sample, as described for 4-point conductivity measurements.


Between the Seebeck coefficient measurement cycles, another measurement is made; current is sent through the sample via top and bottom electrodes and resistance is measured with the middle electrodes. This can be done with either DC or AC measurement device.


With right equipment the Omega software can be used to fully automate the process.


Additionally we provide full systems for combined Seebeck coefficient and conductivity measurements:
