Magnetization and Hall effect studies on the pyrochlore iridate Nd2Ir2O7
S. M. Disseler, S. R. Giblin, Chetan Dhital +3
We present magnetization and Hall effect measurements on the pyrochlore iridate Nd2Ir2O7. Previous muon spin rotation measurements have shown that the system undergoes an unusual t…
Phonon Drag Effect in Nanocomposite FeSb2
Mani Pokharel, Huaizhou Zhao, Kevin Lukas +3
We study the temperature dependence of thermoelectric transport properties of four FeSb2 nanocomposite samples with different grain sizes. The comparison of the single crystals and…
Thermal Stability of Thermoelectric Materials via In Situ Resistivity Measurements
K. C. Lukas, W. S. Liu, Q. Jie +2
An experimental setup for determining the electrical resistivity of several types of thermoelectric materials over the temperature range 20 < T < 550 C is described in detail. One…
Spin ordering and electronic texture in the bilayer iridate SrIrO
Chetan Dhital, Sovit Khadka, Z. Yamani +9
Through a neutron scattering, charge transport, and magnetization study, the correlated ground state in the bilayer iridium oxide SrIrO is explored. Our combined result…
Transport Properties of Ni, Co, Fe, Mn Doped Cu0.01Bi2Te2.7Se0.3 for Thermoelectric Device Applications
Kevin C. Lukas, Weishu Liu, Zhifeng Ren +1
Bi2Te3 based thermoelectric devices typically use a nickel layer as a diffusion barrier to block the diffusion of solder or copper atoms from the electrode into the thermoelectric…
Thermoelectric Properties of Ho-doped Bi1-xSbx
K. C. Lukas, G. Joshi, K. Modic +2
The Seebeck coefficients, electrical resistivities, total thermal conductivities, and magnetization are reported for temperatures between 5 and 350 K for n-type Bi0.88Sb0.12 nano-c…
Experimental Determination of the Lorenz Number in Cu0.01Bi2Te2.7Se0.3 and Bi0.88Sb0.12
K. C. Lukas, W. S. Liu, G. Joshi +5
Nanostructuring has been shown to be an effective approach to reduce the lattice thermal conductivity and improve the thermoelectric figure of merit. Because the experimentally mea…
