Half-Heusler thermoelectric materials: NMR studies
Yefan Tian, Nader Ghassemi, Wuyang Ren +6
We report Co, Nb, and Sb nuclear magnetic resonance (NMR) measurements combined with density functional theory (DFT) calculations on a series of half-Heusler…
Ultralow thermal conductivity from transverse acoustic phonon suppression in distorted crystalline α-MgAgSb
Xiyang Li, Peng-Fei Liu, Enyue Zhao +16
Low thermal conductivity is favorable for preserving the temperature gradient between the two ends of a thermoelectric material in order to ensure continuous electron current gener…
Defect charging and resonant levels in half-Heusler NbTiFeSb
Yefan Tian, Farit G. Vagizov, Nader Ghassemi +5
We report Nb and Sb NMR and Fe Mössbauer studies combined with DFT calculations of NbTiFeSb (), one of the most promisi…
Optical properties of cubic boron arsenide
Bai Song, Ke Chen, Kyle Bushick +6
The ultrahigh thermal conductivity of boron arsenide makes it a promising material for next-generation electronics and optoelectronics. In this work, we report measured optical pro…
Optimizing thermoelectric performances of low-temperature SnSe compounds by electronic structure design
Aijun Hong, Lin Li, Haixia Zhu +3
Recently SnSe compound was reported to have a peak thermoelectric figure-5 of-merit (ZT) of 2.62 at 923 K, but the ZT values at temperatures below 750 K are relatively low. In this…
