Thermoelectric Properties of Ca3xDyxCo3.95Ga0.05O9+d

Thermal properties of Ca3xDyxCo3.95Ga0.05O9+d were quantified, as were the thermoelectric properties. X-ray diffraction was used to determine the phase of the samples. The thermopower of all samples was determined to be positive. The figure of merit and the power factor increased for the samples after doping had occurred....

Low thermal conductivity and enhanced thermoelectric performance of nanostructured Al-doped ZnTe 

This article investigates the effect of aluminum doping on the thermal conductivity and other thermoelectric properties of nanostructured Zn1•XAlXTe (0 ≤ X ≤ 0.15) for a temperature range of 300 K – 600 K. The thermal conductivity was measured using the transient plane source (TPS) technique by a thermal constants analyzer. It was found that with increasing doping of aluminum, the thermal conductivity decreased, and with increasing temperature thermal conductivity also decreased. The decreasing of thermal ...

Enhanced thermoelectric properties of Mg2Si by addition of TiO2 nanoparticles 

Nano-inclusions are thermally conductive particles that improve the thermal conductivity of liquid mediums. In this paper, the thermal properties of Mg2Si were evaluated after the addition of TiO2 nanoparticles. An instrument measured the thermal conductivity of the nanofluid using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluid was the highest at lower temperatures, and did not improve with the addition of the ...

The Effect of Cu2O Nanoparticle Dispersion on the Thermoelectric Properties of n-type Skutterudites

This article studies the effect of dispersion of Cu2O nanoparticles on the thermoelectric properties of Ba0.4Co4Sb12 and Sn0.4Ba0.4Co4Sb12 skutterudites. It was found that the dispersion of these nanoparticles resulted in an increased thermoelectric efficiency due to decreased electrical resistivity and thermal conductivity. The figure of merit for Cu2O dispersed Ba0.4Co4Sb12 reached a maximum value of 0.92 at 573 K. This value represents a ...
