Gangjian Tan,Fengyuan Shi,Shiqiang Hao,Hang Chi,Trevor P. Bailey,Li-Dong Zhao,Ctirad Uher,Chris Wolverton,Vinayak P. Dravid,Mercouri G. Kanatzidis,Mercouri G. Kanatzidis +10 more
TL;DR: A high solubility limit of >9 mol% for MnTe alloying in SnTe is demonstrated, and the room-temperature Seebeck coefficients of Mn-doped SnTe are significantly higher than those predicted by theoretical Pisarenko plots for pure SnTe, indicating a modified band structure.

High-Thermoelectric Performance of Nanostructured Bismuth Antimony Telluride Bulk Alloys
Bed Poudel,Qing Hao,Yi Ma,Yucheng Lan,Austin J. Minnich,Bo Yu,Xiao Yan,Dezhi Wang,Andrew Muto,Daryoosh Vashaee,Xiaoyuan Chen,Jun-Ming Liu,Mildred S. Dresselhaus,Gang Chen,Zhifeng Ren +14 more
TL;DR: Electrical transport measurements, coupled with microstructure studies and modeling, show that the ZT improvement is the result of low thermal conductivity caused by the increased phonon scattering by grain boundaries and defects, which makes these materials useful for cooling and power generation.
