Thermal-Transport
AC Resistivity
  • Measured by using precision DSP current source and phase-sensitive voltage detection.
Thermal Conductivity
  • Measured by applying heat from the heater shoe in order to create a user-specified temperature differential between the two thermometer shoes.
Seebeck Coefficient
  • 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 2T /() of the three measured quantities - thermal conductivity, Seebeck coefficient, and AC electrical resistivity.
