Journal ArticleDOI
Ultralow thermal conductivity and high thermoelectric figure of merit in SnSe crystals
Li-Dong Zhao,Shih Han Lo,Yongsheng Zhang,Hui Sun,Gangjian Tan,Ctirad Uher,Chris Wolverton,Vinayak P. Dravid,Mercouri G. Kanatzidis +8 more
TL;DR: An unprecedented ZT of 2.6 ± 0.3 at 923 K is reported in SnSe single crystals measured along the b axis of the room-temperature orthorhombic unit cell, which highlights alternative strategies to nanostructuring for achieving high thermoelectric performance.
Journal ArticleDOI
Electrical energy storage for transportation—approaching the limits of, and going beyond, lithium-ion batteries
TL;DR: In this article, the authors show that 2 and 5 times higher energy densities are required to meet the performance goals of a future generation of plug-in hybrid-electric vehicles (PHEVs) with a 40-80 mile all-electric range, and all-EVs with a 300-400 mile range, respectively.
Journal ArticleDOI
Ultrahigh power factor and thermoelectric performance in hole-doped single-crystal SnSe
Li-Dong Zhao,Li-Dong Zhao,Gangjian Tan,Shiqiang Hao,Jiaqing He,Yanling Pei,Hang Chi,Heng Wang,Shengkai Gong,Huibin Xu,Vinayak P. Dravid,Ctirad Uher,G. Jeffrey Snyder,Chris Wolverton,Mercouri G. Kanatzidis +14 more
TL;DR: A record high ZTdev ∼1.34, with ZT ranging from 0.7 to 2.0 at 300 to 773 kelvin, realized in hole-doped tin selenide (SnSe) crystals, arises from the ultrahigh power factor, which comes from a high electrical conductivity and a strongly enhanced Seebeck coefficient enabled by the contribution of multiple electronic valence bands present in SnSe.
Journal ArticleDOI
Materials Design and Discovery with High-Throughput Density Functional Theory: The Open Quantum Materials Database (OQMD)
TL;DR: The Open Quantum Materials Database (OQMD) as mentioned in this paper contains over 200,000 DFT calculated crystal structures and will be freely available for public use at http://oqmd.org.
Journal ArticleDOI
The Open Quantum Materials Database (OQMD): assessing the accuracy of DFT formation energies
Scott Kirklin,James E. Saal,Bryce Meredig,Alexander Thompson,Jeff W. Doak,Muratahan Aykol,Stephan Ruhl,Chris Wolverton +7 more
TL;DR: The Open Quantum Materials Database (OQMD) as discussed by the authors is a high-throughput database consisting of nearly 300,000 density functional theory (DFT) total energy calculations of compounds from the Inorganic Crystal Structure Database (ICSD).
