Journal ArticleDOI
Broad temperature plateau for thermoelectric figure of merit ZT>2 in phase-separated PbTe0.7S0.3
Haijun Wu,Li-Dong Zhao,Fengshan Zheng,Di Wu,Y. L. Pei,X. Tong,Mercouri G. Kanatzidis,Jiaqing He +7 more
TL;DR: High average ZT is obtained by synergistically optimized electrical- and thermal-transport properties via carrier concentration tuning, band structure engineering and hierarchical architecturing, and highlights a realistic prospect of wide applications of thermoelectrics.
Journal ArticleDOI
Origin of the high performance in GeTe-based thermoelectric materials upon Bi2Te3 doping.
Di Wu,Li-Dong Zhao,Shiqiang Hao,Qike Jiang,Fengshan Zheng,Jeff W. Doak,Haijun Wu,Hang Chi,Yaniv Gelbstein,Ctirad Uher,Chris Wolverton,Mercouri G. Kanatzidis,Jiaqing He +12 more
TL;DR: It is shown that a remarkably high ZT of ∼1.9 can be achieved at 773 K in Ge0.87Pb0.13Te upon the introduction of 3 mol % Bi2Te3.
Journal ArticleDOI
High thermoelectric performance realized in a BiCuSeO system by improving carrier mobility through 3D modulation doping.
TL;DR: A greatly enhanced thermoelectric performance in a BiCuSeO system is reported, realized by improving carrier mobility through modulation doping, which leads to a broad, high power factor.
Journal ArticleDOI
Origin of low thermal conductivity in SnSe
Yu Xiao,Cheng Chang,Yanling Pei,Di Wu,Kunling Peng,Xiaoyuan Zhou,Shengkai Gong,Jiaqing He,Yongsheng Zhang,Yongsheng Zhang,Zhi Zeng,Zhi Zeng,Li-Dong Zhao +12 more
TL;DR: In this paper, the authors provide direct evidence to understand the origin of low thermal conductivity of lead chalcogenides using elastic measurements, which is attributed to the extremely weak Sn-Se atomic interactions (or bonds between layers).
Journal ArticleDOI
Enhanced Thermoelectric Properties in the Counter-Doped SnTe System with Strained Endotaxial SrTe
Li-Dong Zhao,Xiao Zhang,Haijun Wu,Haijun Wu,Gangjian Tan,Yanling Pei,Yu Xiao,Cheng Chang,Di Wu,Hang Chi,Lei Zheng,Shengkai Gong,Ctirad Uher,Jiaqing He,Mercouri G. Kanatzidis +14 more
TL;DR: enhanced thermoelectric performance in SnTe, where significantly improved electrical transport properties and reduced thermal conductivity were achieved simultaneously are reported, suggesting that SnTe is a robust candidate for medium-temperature thermoelectedric applications.
