TAGS-related indium compounds and their thermoelectric properties – the solid solution series (GeTe)xAgInySb1−yTe2 (x = 1–12; y = 0.5 and 1)
Solid solutions of GeTe, AgInTe2 and optionally AgSbTe2 (accessible via high-pressure synthesis or by quenching, depending on the phases’ In content) exhibit remarkable thermoelectric properties that clearly reflect transitions between metastable and stable phases.

The influence of microstructure on charge separation dynamics in organic bulk heterojunction materials for solar cell applications
We show a strong correlation of the charge separation dynamics by electron and hole transfer with the solid-state microstructure of organic bulk heterojunction materials.
