Rudyk, Brent W.

Several series of quaternary chalcogenides were synthesized by high temperature reactions and their crystal structures were determined by X-ray diffraction methods. Differences in electronic structure were examined by X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge...

Bie, Haiying

This thesis focuses on the synthesis, structures, and physical properties of ternary rare-earth antimonides and germanides. These ternary compounds exhibit diverse polyanionic substructures with classical and non-classical Sb–Sb bonding, Ge–Ge bonding, or both. The Zintl-Klemm concept and band...

Mishra, Vidyanshu

In this thesis, rare-earth-containing chalcogenides and oxychalcogenides were sought with the aim to identify new crystal structures and to evaluate their potential as optical and thermoelectric materials. They were synthesized in the form of pure microcrystalline powders and single crystals...

Ternary and quaternary germanides containing rare-earth and transition metals are of interest because of their structural diversity and the potential for interactions between f- and d-electrons. Within the Ce–Rh–Ge system, three new ternary phases Ce3Rh11Ge5, CeRh5Ge3, and CeRh3Ge2 were prepared...
