Abstract

Electron correlations and intermediate valence distinctly influence electronic transport in skutterudites and hence modify the thermoelectric performance. Kondo interaction remarkably enhances thermopower, and electrons provided, e.g., by intermediate valent Yb may compensate holes of the transition metal?pnictogen units, which then can show thermopower values well above 100 [small mu, Greek] V/K.
