| Research Abstract |
IV based compound semiconductors were grown by mechanical alloying technique and other methods. The crystalline structure and their solid state properties of the compound are were characterized. Especially, the crystalline structure of cubic-CaxSi (x~4) was mainly examined by XRD, STEM with EDS, and its solid state properties were characterized by IR transmission spectrum, XPS, TG-DTA, Raman spectroscopy. It was demonstrated that new solid state properties of the compound were obtained. In addition, the temperature dependence of Seebeck coefficient and Resistivities of the compound was measured for the thermoelectric application. Moreover, the structural modifications are under investigation using the following nanostructure fabrications; metastable hexagoal-MoSi2nanosheets, CrSi2 nanowire bundle and dendrite structures, Mg2Ge, Mg2SiGe rods, and so on．
