Thermoelectric properties of nanoporous Ge
We computed thermoelectric properties of nanoporous Ge !np-Ge" with aligned pores along the #001$ direction through a combined classical molecular dynamics and first-principles electronic structure approach. A significant reduction in the lattice thermal conductivity of np-Ge leads to a 30-fold increase in the thermoelectric figure-of-merit !ZT" compared to that of bulk. Detailed comparisons wi...

Thermoelectric Properties of Highly-Crystallized Ge-Te-Se Glasses Doped with Cu/Bi
Chalcogenide semiconducting systems are of growing interest for mid-temperature range (~500 K) thermoelectric applications. In this work, Ge20Te77Se₃ glasses were intentionally crystallized by doping with Cu and Bi. These effectively-crystallized materials of composition (Ge20Te77Se₃)100-xMx (M = Cu or Bi; x = 5, 10, 15), obtained by vacuum-melting and quenching techniques, were found to have m...
متن کاملSynthesis, structure, magnetism, and high temperature thermoelectric properties of Ge doped Yb14MnSb11.
The Zintl phase Yb(14)MnSb(11) was successfully doped with Ge utilizing a tin flux technique. The stoichiometry was determined by microprobe analysis to be Yb(13.99(14))Mn(1.05(5))Sb(10.89(16))Ge(0.06(3)). This was the maximum amount of Ge that could be incorporated into the structure via flux synthesis regardless of the amount included in the reaction. Single crystal X-ray diffraction could no...
متن کاملThermoelectric Properties of Lanthanum-Doped Europium Titanate
The thermoelectric properties of lanthanum-doped polycrystalline perovskite-type europium titanate were measured from room temperature to 900K and compared to those of MTiO3 (M 1⁄4 Ca, Sr, Ba). The differences in the titanates were calculated in terms of the differences of A-site ion and Ti–O distance that determined the covalent bonding strength. The A-site ion appeared to have little influenc...
