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.
