High temperature charge and thermal transport properties of the n-type thermoelectric material PbSe
John Androulakis, Duck-Young Chung, Xianli Su +6
We present a detailed study of the charge transport, optical reflectivity, and thermal transport properties of n-type PbSe crystals. A strong scattering, mobility-limiting mechanis…
Thermoelectric enhancement in PbTe with K, Na co-doping from tuning the interaction of the light and heavy hole valence bands
John Androulakis, Iliya Todorov, Duck-Young Chung +4
The effect of K and K-Na substitution for Pb atoms in the rock salt lattice of PbTe was investigated to test a hypothesis for development of resonant states in the valence band tha…
Phase separation and nanostructuring in the thermoelectric material PbTe1-xSx
H. Lin, E. S. Bozin, S. J. L. Billinge +3
The average and local structures of the (PbTe)1-x(PbS)x system of thermoelectric materials has been studied using the Rietveld and atomic pair distribution function (PDF) methods.…
La0.95Sr0.05CoO3: An efficient room-temperature thermoelectric oxide
J. Androulakis, P. Migiakis, J. Giapintzakis
We present measurements of electrical resistivity, thermal conductivity and thermopower of polycrystalline Sr-doped LaCoO3 with composition La0.95Sr0.05CoO3. Our data show that the…
Unconventional magnetism in all-carbon nanofoam
A. V. Rode, E. G. Gamaly, A. G. Christy +7
We report production of nanostructured carbon foam by a high-repetition-rate, high-power laser ablation of glassy carbon in Ar atmosphere. A combination of characterization techniq…
Magnetoresistance and percolation in the LaNi(1-x)Co(x)O3 solid solution
J. Androulakis, Z. Viskadourakis, N. Katsarakis +1
A detailed study of the zero-field electrical resistivity and magnetoresistance for the metallic members of the LaNi_{1-x}Co{x}O3 solid solution with 0.3<=x<=0.6 is reported. The l…
