Copper Selenide is one of the promising single crystal thermoelectric material for power generation in low temperature range 300 - 360 K. Universal testing machine is used for pressing the Nano powder to obtain the Nano bulk samples. By using X-ray diffraction (XRD) and scanning electronic microscope (SEM) identified the structure and phase composition. This study shown that 150 kN pressing force in sample without carbon nano tubes showed ZT=1.2 at a temperature of 322K. It is also shown that thermal conductivity and power factor is mainly influencing the value of thermoelectric efficiency of the studied materials.

Abstract


Copper Selenide is one of the promising single crystal thermoelectric material for power generation in low temperature range 300 - 360 K. Universal testing machine is used for pressing the Nano powder to obtain the Nano bulk samples. By using X-ray diffraction (XRD) and scanning electronic microscope (SEM) identified the structure and phase composition. This study shown that 150 kN pressing force in sample without carbon nano tubes showed ZT=1.2 at a temperature of 322K. It is also shown that thermal conductivity and power factor is mainly influencing the value of thermoelectric efficiency of the studied materials.
