Thermoelectric Properties of Gadolinium Copper Tellurides
ثبت نشده
چکیده
Since thermoelectrics are an important way to produce electricity from waste heat, the thermoelectric properties of gadolinium copper telluride, GdCuTe2, together with the doped compounds gadolinium samarium copper telluride, Gd1-xSmxCuTe2, and gadolinium dysprosium copper telluride, Gd1-xDyxCuTe2, with x = 0.02 and x = 0.05 were investigated. Upon doping, a decrease in thermal conductivity and an increase in electrical conductivity were observed leading to an improved figure of merit for the heavily doped samples. An interesting peak around 200°C in the electrical conductivity was also found, stimulating further research into the cause of this nonlinear trend, which will hopefully be done in the future.

Heterostructures of skutterudites and germanium antimony tellurides structure analysis and thermoelectric properties of bulk samples
Heterostructures of germanium antimony tellurides with skutterudite-type precipitates are promising thermoelectric materials due to low thermal conductivity and multiple ways of tuning their electronic transport properties. Materials with the nominal composition [CoSb2(GeTe)0.5]x(GeTe)10.5Sb2Te3 (x = 0–2) contain nanoto microscale precipitates of skutterudite-type phases which are homogeneously...

Abstract: In this work we investigate the electronic, optical, dynamic and thermoelectric properties of ternary copper-based Chalcogenides CuSbX2 (X= S, Se) compounds. Calculations are based on density functional theory and the semi-classical Boltzmann theory. Computations have been carried out by using Quantum-Espresso (PWSCF) package and ab-initio pseudo-potential technique. To estimate the e...
متن کاملInfluence of strain on anisotropic thermoelectric transport in Bi2Te3 and Sb2Te3
On the basis of detailed first-principles calculations and semiclassical Boltzmann transport, the anisotropic thermoelectric transport properties of Bi2Te3 and Sb2Te3 under strain were investigated. It was found that due to compensation effects of the strain-dependent thermopower and electrical conductivity, the related power factor will decrease under applied in-plane strain for Bi2Te3, while ...
متن کاملInfluence of Compensating Defect Formation on the Doping Efficiency and Thermoelectric Properties of Cu2‐ySe1−xBrx
The superionic conductor Cu2−δSe has been shown to be a promising thermoelectric at higher temperatures because of very low lattice thermal conductivities, attributed to the liquid-like mobility of copper ions in the superionic phase. In this work, we present the potential of copper selenide to achieve a high figure of merit at room temperature, if the intrinsically high hole carrier concentrat...

We report the thermal behavior of gadolinium foils to be used in magneto thermoelectric generator cells. Magneto thermoelectric generator cell technology exploits the ferromagnetic phase transition of gadolinium to drive the movement of a diaphragm ‘shuttle’ whose mechanical energy is converted to electrical form and which enhances heat transfer through both conduction and convection. Efficient...
