Thermal Transport Option

AC Resistivity ρ

  • Measured by using precision DSP current source and phase-sensitive voltage detection (AC Transport).

Thermal Conductivity κ

  • Measured by applying heat from the heater shoe in order to create a user-specified temperature differential between the two thermometer shoes.

Seebeck Coefficient α

  • Measured by creating a specified temperature drop between the two thermometer shoes - just as it does to measure thermal conductivity. However, for Seebeck coefficient the voltage drop created between the thermometer shoes is also monitored.

Thermoelectric Figure of Merit ZT

  • Determined here simply as the algebraic combination α2T /(κρ) of the three measured quantities - thermal conductivity, Seebeck coefficient, and AC electrical resistivity.
