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.

Improved Thermoelectric Power Factor in Metal-Based Superlattices
Daryoosh Vashaee,Ali Shakouri +1 more
TL;DR: It is shown that metal-based superlattices with tall barriers can achieve a large effective thermoelectric figure of merit (ZT > 5 at room temperature), a key parameter to achieving high performance is the nonconservation of lateral momentum during the thermionic emission process.
Journal ArticleDOI
Demonstration of electron filtering to increase the Seebeck coefficient in In 0.53 Ga 0.47 As ∕ In 0.53 Ga 0.28 Al 0.19 As superlattices
Joshua M. O. Zide,Daryoosh Vashaee,Zhixi Bian,Gehong Zeng,John E. Bowers,Ali Shakouri,Arthur C. Gossard +6 more
TL;DR: In this paper, the authors explore electron filtering as a technique to increase the Seebeck coefficient and the thermoelectric power factor of heterostructured materials over that of the bulk.
