Electrical conductivity and thermoelectric power of the compounds (

چکیده
The electrical conductivity, U, and thermoelectric power, S , of the solid solutions (Dy,Y,-x)2M0207 have been measured in the temperature range 300-10 K. Log(aT) versus 1/T and S versus 1/T plots were found to be linear down to about 100 K. The activation energies E, and Es obtained from conductivity and thermoelectric power measurements, respectively, differ by one order of magnitude, indsating the presence of a thermally activated mobility. Below 100 K, even though log(uq\/T) versus T-'I4 plots were linear, the Mott parameters were found to be physically unrealistic. The overall conductivity behaviour can, however, be explained in terms of hopping of small polarons.

Ab-initio study of Electronic, Optical, Dynamic and Thermoelectric properties of CuSbX2 (X=S,Se) compounds
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...

Solid-state energy conversion technologies such as thermoelectric refrigeration and power generation require materials with low thermal conductivity yet high electrical conductivity and Seebeck coefficiency. Although semiconductors are the best thermoelectric materials, they rarely have the such features. Nanostructures such as superlattices, quantum wires, and quantum dots provide novel method...

متن کاملLoad Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator
The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
