High-performance bulk thermoelectrics with all-scale hierarchical architectures
Kanishka Biswas,Jiaqing He,Ivan Blum,Ivan Blum,Chun I. Wu,Timothy P. Hogan,Timothy P. Hogan,David N. Seidman,Vinayak P. Dravid,Mercouri G. Kanatzidis,Mercouri G. Kanatzidis +10 more
TL;DR: It is shown that heat-carrying phonons with long mean free paths can be scattered by controlling and fine-tuning the mesoscale architecture of nanostructured thermoelectric materials, and an increase in ZT beyond the threshold of 2 highlights the role of, and need for, multiscale hierarchical architecture in controlling phonon scattering in bulk thermoeLECTrics.
Journal ArticleDOI
Cubic AgPbmSbTe2+m: Bulk Thermoelectric Materials with High Figure of Merit
Kuei Fang Hsu,Sim Loo,Fu Guo,Wei Chen,Jeffrey S. Dyck,Ctirad Uher,Timothy P. Hogan,Efstathios K. Polychroniadis,Mercouri G. Kanatzidis +8 more
TL;DR: In the temperature range 600 to 900 kelvin, the AgPbmSbTe2+m material is expected to outperform all reported bulk thermoelectrics, thereby earmarking it as a material system for potential use in efficient thermoeLECTric power generation from heat sources.
Journal ArticleDOI
CsBi4Te6: A High-Performance Thermoelectric Material for Low-Temperature Applications
Duck Young Chung,Timothy P. Hogan,Paul Brazis,Melissa Rocci-Lane,Carl R. Kannewurf,Marina Bastea,Ctirad Uher,Mercouri G. Kanatzidis +7 more
TL;DR: The material CsBi(4)Te(6) has been synthesized and its properties have been studied, and at cryogenic temperatures, the thermoelectric properties appear to match or exceed those of Bi(2-x)Sb(x)Te (3-y)Se(y) alloys.
Journal ArticleDOI
All-scale hierarchical thermoelectrics: MgTe in PbTe facilitates valence band convergence and suppresses bipolar thermal transport for high performance
Li-Dong Zhao,Haijun Wu,Shiqiang Hao,Chun I. Wu,Xiaoyuan Zhou,Kanishka Biswas,Jiaqing He,Timothy P. Hogan,Ctirad Uher,Chris Wolverton,Vinayak P. Dravid,Mercouri G. Kanatzidis +11 more
TL;DR: In this paper, the authors reported a high ZT of ∼2.0 at 823 K for 2% Na-doped PbTe with 6% MgTe with excellent thermal stability.
Journal ArticleDOI
Spinodal Decomposition and Nucleation and Growth as a Means to Bulk Nanostructured Thermoelectrics: Enhanced Performance in Pb1-xSnxTe-PbS
John Androulakis,Chia Her Lin,Hun Jin Kong,Ctirad Uher,Chun I. Wu,Timothy P. Hogan,Bruce A. Cook,Thierry Caillat,Konstantinos M. Paraskevopoulos,Mercouri G. Kanatzidis,Mercouri G. Kanatzidis +10 more
TL;DR: The relative importance of the two observed modes of nanostructuring, spinodal decomposition and nucleation and growth, in suppressing the thermal conductivity was assessed in this work, and it can conclude that the latter mode seems more effective in doing so.
