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.

Xiaofeng Fan,Gehong Zeng,Chris LaBounty,John E. Bowers,Edward T. Croke,Channing C. Ahn,Scott T. Huxtable,Arun Majumdar,Ali Shakouri +8 more
TL;DR: SiGeC/Si superlattice microcoolers with dimensions as small as 40×40 µm^2 were fabricated and characterized in this article, where they were grown on Si substrates by molecular beam epitaxy and thermal conductivity was measured by the 3omega method.

TL;DR: In this paper, the cross-plane lattice and electronic thermal conductivities of superlattices made of InGaAlAs and InGaAs films, with the latter containing embedded ErAs nanoparticles (denoted as ErAs:InGaAs), were studied.
Thermoelectric power generator module of 16×16 Bi2Te3 and 0.6% ErAs:(InGaAs)1−x(InAlAs)x segmented elements
Gehong Zeng,Je-Hyeong Bahk,John E. Bowers,Hong Lu,Arthur C. Gossard,Suzanne L. Singer,Arun Majumdar,Zhixi Bian,Mona Zebarjadi,Ali Shakouri +9 more
TL;DR: In this paper, the fabrication and characterization of thermoelectric power generator modules of 16×16 segmented elements consisting of 0.8 mm thick Bi2Te3 and 50 µm thick ErAs with 0.6% ErAs by volume was reported.

High-power-density spot cooling using bulk thermoelectrics
TL;DR: In this article, a 3D bulk silicon microcooler was demonstrated, which has the advantages of high cooling power densities and is less dependent on thermoelectric element's thickness as compared with the same device with 1D geometry.
