نویسنده
چکیده
(y)Ni0.7Co0.3Fe2O4 + (1-y) Ba0.7Pb0.3TiO3 composites were prepared using ceramic method. The phase analysis was carried out by X-ray diffraction technique. It has confirmed that no impurity phase is present in the composites. The dc resistivity, thermo emf studied as a function of temperature. The value of static magnetoelectric conversion factor, i.e. dc (ME)H studied as a function of magnetic field. The maximum value of ME coefficient was observed for y=0.30 composite, whereas minimum for y=0.15 composite. Keywords— Composites, Conductivity, ME effect, Resistivity, Tep.

Carbon fiber polymer–matrix structural composites exhibiting greatly enhanced through-thickness thermoelectric figure of merit
The through-thickness thermoelectric behavior of continuous carbon fiber epoxy-matrix composites is greatly improved by adding tellurium particles (13 vol.%), bismuth telluride particles (2 vol.%) and carbon black (2 vol.%). The thermoelectric power is increased from 8 to 163 lV/K, the electrical resistivity is decreased from 0.17 to 0.02.X.cm, the thermal conductivity is decreased from 1.31 to...

متن کاملEnhanced thermoelectric properties of solution grown Bi2Te(3-x)Se(x) nanoplatelet composites.
We report on the enhanced thermoelectric properties of selenium (Se) doped bismuth telluride (Bi(2)Te(3-x)Se(x)) nanoplatelet (NP) composites synthesized by the polyol method. Variation of the Se composition within NPs is demonstrated by X-ray diffraction and Raman spectroscopy. While the calculated lattice parameters closely follow the Vegard's law, a discontinuity in the shifting of the high ...
