I have worked on the same compounds than previously (Mg2Si-based compounds) and on (Bi,Sb)2Te3. I have studied on another way to make them dense: Hot extrusion. The samples were characterized by X-Ray diffraction and Scanning Electron Microscopy (SEM). Then the thermoelectric properties were measured by Harman measurement. A part of my work consisted also on improving the electrical contact on Mg2Si-based compounds for the Harman measurements.

Projects : -THERMOMAG : http://www.thermomag-project.eu/partners.html -RENOTER 2 : http://www.id4car.org/RENOTER-2.html I was in charge of the solid state synthesis and the hot pressing of Mg2Si-based compounds. The quality of the samples was checked by X-Ray diffraction (Rietveld refinements) and the thermoelectric properties were measured. I have also studied the thermal stability of the Mg2Si1-xSnx compounds using several techniques (T-dependent X-Ray Diffraction, TGA, Annealing).
