Surface composition of ordered alloys: An off-stoichiometric effect

Thermoelectric properties of the Heusler-type off- stoichiometric Fe2V1+xAl1-x alloys

We report the thermoelectric properties of Heusler-type off-stoichiometric Fe2V1+xAl1-x alloys. Due to the off-stoichiometric effect, which is the substitution of V/Al atoms with Al/V atoms, semiconductor-like electric resistivity behavior in Fe2VAl is changed to metallic behavior in Fe2V1+xAl1-x alloys and both positive and negative absolute Seebeck coefficients are drastically increased. The ...

CdTe And CdTe : Hg alloys crystal growth using stoichiometric and off-stoichiometric zone passing techniques

2014 Some aspects of the thermodynamic state of CdTe crystals grown by different zone passing techniques (sealed ingot zone refining technique and THM in tellurium solvent) are considered with regard to the general objective of getting high resistivity crystals. A vapour growth technique, called sublimation THM, which reduces several drawbacks of classical THM using a tellurium solvent, is deve...

The Off-Stoichiometric Bi1.8Pb0.3Sr2Ca2Cu3.3Ox Target for Thin Films

X-ray diffraction (XRD), EDAX, AC susceptibility and resistivity measurements has been used as characterization methods for the Bi-2223 monophase target with the starting stoichiometry Bil.8F%,.3Sr2Ca2C~3.3 a. Pressure parameter is playing an important role in obtaining good superconducting properties for this compound. Critical currents and activation energy has been calculated from susceptibi...
