Journal ArticleDOI
Phonon engineering through crystal chemistry
TL;DR: In this paper, the origins of low thermal conductivity in crystalline materials are discussed and a unifying feature in the latest materials is the incorporation of structural complexity to decrease the phonon velocity and increase scattering.
Journal ArticleDOI
Thinking Like a Chemist: Intuition in Thermoelectric Materials.
Wolfgang G. Zeier,Alex Zevalkink,Zachary M. Gibbs,Geoffroy Hautier,Mercouri G. Kanatzidis,G. Jeffrey Snyder +5 more
TL;DR: An overview of how symmetry and bonding strength affect electron and phonon transport in solids, and how altering these properties may be used in strategies to improve thermoelectric performance is provided.
Journal ArticleDOI
A practical field guide to thermoelectrics: Fundamentals, synthesis, and characterization
Alex Zevalkink,David M. Smiadak,Jeffrey L. Blackburn,Andrew J. Ferguson,Michael L. Chabinyc,Olivier Delaire,Olivier Delaire,Jian Wang,Jian Wang,Kirill Kovnir,Kirill Kovnir,Joshua Martin,Laura T. Schelhas,Taylor D. Sparks,Stephen Dongmin Kang,Maxwell Dylla,G. Jeffrey Snyder,Brenden R. Ortiz,Eric S. Toberer +18 more
TL;DR: In this article, the authors present a review of the state-of-the-art in the field of thermoelectric materials with a focus on bulk inorganic materials, including powder and single crystal synthesis, error analysis, and modeling of transport data using an effective mass model.
Journal ArticleDOI
Thermoelectric properties of Sr3GaSb3 – a chain-forming Zintl compound
Alex Zevalkink,Wolfgang G. Zeier,Wolfgang G. Zeier,Gregory Pomrehn,Eugen Schechtel,Wolfgang Tremel,G. Jeffrey Snyder +6 more
TL;DR: In this article, the authors investigated the thermoelectric properties of the closely related compound Sr3GaSb3 and showed that it is a non-degenerate semiconductor with relatively high p-type electronic mobility (∼30 cm2 V−1 s−1 at 300 K).
Journal ArticleDOI
Achieving zT > 1 in Inexpensive Zintl Phase Ca9Zn4+xSb9 by Phase Boundary Mapping
Saneyuki Ohno,Saneyuki Ohno,Umut Aydemir,Maximilian Amsler,Jan-Hendrik Pöhls,Sevan Chanakian,Alex Zevalkink,Mary Anne White,Sabah K. Bux,Chris Wolverton,G. Jeffrey Snyder,G. Jeffrey Snyder +11 more
TL;DR: In this paper, the authors show that the defect concentrations can be tuned with small variation of the chemical potentials (composition) of each element in complex multinary compounds (ternary, quaternary, and higher) by mapping the boundaries where different competing impurity phases form.
