Resistivity and Thermopower High Temperature Probe High temperature thermopower and resistivity measurements of bulk, amorphous, and single crystal materials are made with the custom-built High Temperature Probe. Samples are mounted in one of two arrangements. The current leads are attached as close to the end of the sample as possible. Thermopower and resistivity are measured within the same sample run.
Resistance is measured by injecting a current and measuring the voltage.
The resistivity is calculated from the resistance. The High Temperature Probe can measure one sample in approximately four hours. There are several probe heads so that samples can be mounted while another sample is being measured. The CAML has two systems.
