Tailoring the amount of nanometer-sized nodules made of amorphous silica, resulting from natural oxidation during the processing steps, in an N-type sintered polycrystalline Si92Ge08 material is shown as an effective way to reduce the thermal conduct

International audience; An N-type Si92Ge08 (7000 at. ppm P doping) powder (matrix) prepared by mechanical alloying was homogeneously mixed with 1.3 vol.% nanosized molybdenum. The "composite" and matrix powders were sintered by spark plasma sintering
