Abstract
Provided is an apparatus for measuring a thermoelectric device. The apparatus includes a high temperature heater controlling a temperature of a first side of a sample, a low temperature heater controlling a temperature of a second side of the sample, a fine control heater controlling the temperature of the first side of the sample by a smaller unit than the high temperature heater, a temperature control and voltage measuring unit controlling the high temperature heater, the low temperature heater, and the fine control heater and measuring voltages of the first and second sides of the sample, and a thermal conductivity measuring unit measuring thermal conductivity of the sample by using a high temperature output voltage generated in the first side of the sample and a low temperature output voltage generated in the second side of the sample.
