Influence of Lattice Polarizability on the Ionic Conductivity in the Lithium Superionic Argyrodites Li6PS5X (X = Cl, Br, I)
Marvin A. Kraft,Sean P. Culver,M. Calderon,Felix Böcher,Thorben Krauskopf,Anatoliy Senyshyn,Christian Dietrich,Alexandra Zevalkink,Jürgen Janek,Wolfgang G. Zeier +9 more
TL;DR: These results show that the lattice softness has a striking influence on the ionic transport: the softer bonds lower the activation barrier and simultaneously decrease the prefactor of the moving ion.
Journal ArticleDOI
Thermoelectrics: From history, a window to the future
Davide Beretta,Davide Beretta,Neophytos Neophytou,James M. Hodges,Mercouri G. Kanatzidis,Dario Narducci,Marisol Martin Gonzalez,Matt Beekman,Benjamin Balke,Giacomo Cerretti,Wolfgang Tremel,Alexandra Zevalkink,Anna I. Hofmann,Christian Müller,Bernhard Dörling,Mariano Campoy-Quiles,Mario Caironi +16 more
TL;DR: A broad review of thermoelectric materials can be found in this article, where the authors discuss the major steps in the history of thermophysics, from the very early discovery to present technology.
Journal ArticleDOI
Ca3AlSb3: an inexpensive, non-toxic thermoelectric material for waste heat recovery
TL;DR: In this article, the authors demonstrate the use of elementary solid-state chemistry and physics to guide the search and optimization of thermoelectric materials with unusual structures containing abundant and benign elements.
Journal ArticleDOI
The Zintl Compound Ca5Al2Sb6 for Low‐Cost Thermoelectric Power Generation
TL;DR: In this article, the structural complexity of Zintl compounds is implicated in their unusually low thermal conductivity values, and a single parabolic band model is developed and predicts that Ca_(4.75)Na_(0.25)Al_2Sb_6 possesses a near-optimal carrier concentration for thermoelectric power generation.
Journal ArticleDOI
Glass-like lattice thermal conductivity and high thermoelectric efficiency in Yb9Mn4.2Sb9
Sabah K. Bux,Alexandra Zevalkink,Oliver Janka,David Uhl,Susan M. Kauzlarich,Jeffrey Snyder,Jean-Pierre Fleurial +6 more
TL;DR: In this paper, the thermoelectric properties of Yb-9Mn_(4.2)Sb_9 have been investigated, and it has been shown that it is a degenerate p-type semiconductor.
