Keywords:thermopower

One methods of measuring thermopower is by directly measuring the emf of a sample. However, the value is the difference between the thermopower of the wiring to be measured. A possible way to avoid this problem, would be to make measurements using superconducting state, but this is difficult. Therefore, we propose a method of measuring thermopower without using superconducting state. It is based on temperature measurement using an IR camera and a calculation formula for Peltier heat transport.
