چکیده
Heusler-type Fe2AlVxTi1-x alloys offer an alternative solution for the generation of thermoelectric power near room temperature. In current research, properties p-type Fe2AlV0.9Ti0.1 and Fe2AlV0.9Ti0.1/CNT alloys, prepared by SPS, were studied. Carbon nanotubes (CNT) used as dopants to improve seebeck coefficient electrical conductivity. Upon doping with CNT, thermal conductivity was significantly reduced, meanwhile, value factor increased from 0.45 1.55 mW/mK2 at around 330 K. The effect CNT inclusions on parameters Fe2AlVxTi 1-x compounds systematically When compared Fe2AlV0.9Ti0.1, which had a figure merit just 0.02 K, CNT-containing samples showed improved up 0.07. We novel technique performance Fe2AlV alloys.

High-thermoelectric performance of nanostructured bismuth antimony telluride bulk alloys.
The dimensionless thermoelectric figure of merit (ZT) in bismuth antimony telluride (BiSbTe) bulk alloys has remained around 1 for more than 50 years. We show that a peak ZT of 1.4 at 100 degrees C can be achieved in a p-type nanocrystalline BiSbTe bulk alloy. These nanocrystalline bulk materials were made by hot pressing nanopowders that were ball-milled from crystalline ingots under inert con...
متن کاملThermoelectric Properties of In0.3Ga0.7N Alloys
We report on the experimental investigation of the potential of InGaN alloys as thermoelectric (TE) materials. We have grown undoped and Si-doped In0.3Ga0.7N alloys by metalorganic chemical vapor deposition and measured the Seebeck coefficient and electrical conductivity of the grown films with the aim of maximizing the power factor (P). It was found that P decreases as electron concentration (...

The effects of Ge partial substitution for Si on the thermoelectric properties of CoSi1−xGex alloys were investigated by means of thermal and electrical transport measurements. Electrical resistivity , Seebeck coefficient S , and thermal conductivity measurements were performed on a series of CoSi1−xGex alloys with x varying from 0 to 0.15. A substantial decrease in electrical resistivity and l...
متن کاملObstacles to applications of nanostructured thermoelectric alloys
A major theme in thermoelectric research is based on controlling the formation of nanostructures that occur naturally in bulk intermetallic alloys through various types of thermodynamic phase transformation processes (He et al., 2013). The question of how such nanostructures form and why they lead to a high thermoelectric figure of merit (zT) are scientifically interesting and worthy of attenti...
متن کاملCoefficient of Performance Optimization of a Single Stage Thermoelectric Cooler
In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, ...
