System for measuring high temperature thermoelectric properties


This in-house system is used to measure electrical resistivity and Seebeck coefficient (a.k.a. thermopower) between room temperature and 1300 K. The system employs the four-probe method - four electrical/thermal probes are mechanically pressed on a sample, typically a bar about 2 mm wide and 8 mm long. Measurements can be performed under nitrogen flow.
