Eco-friendly high-performance silicide thermoelectric materials
Silicide-based thermoelectrics are examples of cost-efficient and environmentally friendly new energy materials, which can be used for power-generation applications in the range of 500–800 K. We review the research focusing on the exploration of n-typeMg2IV-based solid solutions (IV= Si, Ge and Sn) and summarize the most prominent discoveries achieved so far in their studies. Owing to their sup...
متن کاملThermodynamical study of the thermoelectric effect for magnesium silicide.
The thermoelectric effect of magnesium silicide is studied by using a thermodynamical method in the presence of an electric field. The thermoelectric potential is evaluated from the partial derivative of free energy with respect to charge in which the free energy is calculated at the B3LYP/6-31G(d,p) level of density functional theory. This free energy is also utilized to determine the average ...
متن کاملThermoelectric Performance of Na-Doped GeSe
Recently, hole-doped GeSe materials have been predicted to exhibit extraordinary thermoelectric performance owing largely to extremely low thermal conductivity. However, experimental research on the thermoelectric properties of GeSe has received less attention. Here, we have synthesized polycrystalline Na-doped GeSe compounds, characterized their crystal structure, and measured their thermoelec...
متن کاملThermoelectric Properties of Lanthanum-Doped Europium Titanate
The thermoelectric properties of lanthanum-doped polycrystalline perovskite-type europium titanate were measured from room temperature to 900K and compared to those of MTiO3 (M 1⁄4 Ca, Sr, Ba). The differences in the titanates were calculated in terms of the differences of A-site ion and Ti–O distance that determined the covalent bonding strength. The A-site ion appeared to have little influenc...
متن کاملThermoelectric Properties of Doped Zigzag Silicene Nanoribbons
Thermoelectric properties of silicene nanoribbons doped with magnetic impurity atoms are investigated theoretically for both antiparallel and parallel orientations of the edge magnetic moments. Spin density distribution and transport parameters have been determined by ab-initio numerical methods based on the density functional theory. Doping with magnetic atoms considerably modi es the spin den...
