A new system to measure the electrical conductivity and the Hall constant for high temperature characterization is presented here. A new sample holder with a screen-printed platinum heater and four moveable electrodes allow measurements of any geometry according to van der Pauw’s method up to 600 °C. The new design also enables the use of low-cost permanent magnets. Measurements of a gold thin-film and a boron-doped silicon-wafer demonstrate the functionality of the measurement system.
Further developments will add the possibility to measure the Seebeck coefficient.
