Abstract Scope |
Our previous studies of complex chromium chalcogenides (Ch) in the pseudo hollandite structure type have led to the discovery of new phases and interesting features that triggered our interest to explore further other transition metal chalcogenides. In this presentation, our latest results on light transistion metal selenides and tellurides will be shown. For instance, the niobium rich part of the binary phase diagram Nb - Ch will be discussed in detail and the presence of a eutectoide transformation debated. In this system, we will present our synthesis strategy and we will also show the transport properties of some niobium rich phases that might be find their interest at very high temperature. |
