| Abstract Scope |
Here, we will present our recent activities on structurally disordered materials made of transition metal-based chalcogenides and phosphides. Our focus is on compositions exhibiting promising features for thermoelectric applications. For instance, the misfit layered sulfide (La1-xCexS)z(NbS2) which are of interest due to the unique opportunities they offer for ZT enhancement arising from their phonon glass-electron crystal (PGEC) behavior. Additionally, we will discuss another group of materials, namely copper phosphides, which are notable for their abundance of elements and reported low gravimetric density. These materials, which can be conveniently doped n or p-type, exhibit large power factors and hold significant promise in terms of figures of merit. |
