TL;DR: The results firmly show that high power factors can be realized by adjusting the total filling fraction of fillers with different charge states to reach the optimum carrier density, and lattice thermal conductivity can also be significantly reduced, to values near the glass limit of these materials.

TL;DR: In this paper, the combination of Ba and Yb fillers inside the voids of the skutterudite structure provides a broad range of resonant phonon scattering and consequently a strong suppression in the lattice thermal conductivity.

TL;DR: In this paper, the authors investigated low and high temperature thermoelectric properties by measuring the electrical conductivity, Seebeck coefficient, thermal conductivity and Hall coefficient between 2 K and 900 K.

TL;DR: In this article, the Zintl-Klemm rule is demonstrated to be valid for Ni, Cu, and Zn transition metal substitution in the framework of type I clathrates and offers many degrees of freedom for material modification, design, and optimization.

TL;DR: In this article, the authors show that both H+/Zn2+ intercalation and conversion reactions occur at different voltages and that the rapid capacity fading can clearly be attributed to the rate-limiting and irreversible conversion reactions at a lower voltage.
