My main subject is to set up a measuring system of TEP(Thermoelectric Power) which the theory was based on Thomas Seebeck effect, mechanism of the translation between thermal energy and electricity. There are two applications of thermoelectric power. One is temperature dependent measurement which is applied on thermal couple sensor; another one is to study the thermoelectric materials. The Seebeck coeifficient is approached to zero when superconductivity was occurred, also the calibration of the obtained value and offers essential information of carriers.
The hardware of thermoelectric power measuring system consists of Digital NanoVoltmeter¡BProgrammable current Source¡BTemperature controller and Cryogenic compressor system. In the software, we use LabView to control the integral system and analyze the obtained data. For the whole system, it is vital to find a suitable compositions of sample holder¡Bheater and pasted way of sample.
