Thermal conductivity of Ni, Co, and Fe-doped La5Ca 9Cu24O41 thin films measured by the 3ω method
(2010)
The effect of Ni-, Co- and Fe-substitution for Cu on the thermal conductivity of La5Ca9Cu24O41 thin films is investigated. Highly b-axis oriented polycrystalline films were grown onto MgO (100) substrates using the pulsed ...
Pulsed laser deposition and thermal characterization of Ni-doped La5Ca9Cu24O41 thin films
(2011)
Highly b-axis oriented polycrystalline Ni-doped La5Ca 9Cu24O41 thin films have been grown on (0 0 1) SrTiO3 substrates using the pulsed laser deposition technique. EDX measurements have revealed nearly stoichiometric ...
Recent advances in spintronics. Half-metal ferromagnets: Their role in spintronics
(2004)
A review of recent advances in spintronics is presented. We report the structural, magnetic, electrical and thermal properties of the ferromagnetic half-Heusler alloy NiMnSb grown by arcmelting. The bulk material is used ...
Experimental determination of the absolute temperature modulation in photothermal microscopy of Y1Ba2Cu3O7 crystals
(1997)
We present a technique to experimentally determine the value of the temperature perturbation ST in photothermal microscopy. Knowledge of δT is necessary for proper analysis of the differential optical reflectivity (∂R/∂T) ...
Effect of antimony-doping and germanium on the highly efficient thermoelectric Si-rich-Mg2(Si,Sn,Ge) materials
(2017)
Two series of materials (a) Mg2Si0.55-ySn0.4Ge0.05Sby, 0 ≤ y ≤ 0.0175 and (b) Mg2Si0.5875-xSn0.4GexSb0.0125, 0 ≤ x ≤ 0.20 have been developed and studied in terms of structural features and thermoelectric properties/performance. ...
La0.95Sr0.05Coo3: An efficient room-temperature thermoelectric oxide
(2004)
Electric resistivity, thermal conductivity, and the thermopower of polycrystalline Sr-doped LaCoO3 with composition La 0.9Sr0.5CoO3 were measured. The crystal structure of the synthesized powders was determined by x-ray ...
Synthesis and physical properties of arc melted NiMnSb
(2004)
The synthesis and physical properties of arc melted NiMnSb were studied using X-ray diffraction analysis. It was observed that the half metallicity in NiMnSb is supported by the integer saturation magnetization value at 5 ...
Structural Characterization and Thermoelectric Properties of Hot-Pressed CoSi Nanocomposites
(2014)
Fabrication of nanocomposites by introduction of SiO2 metal oxide nanoparticles into a cobalt silicide thermoelectric matrix is studied. The CoSi matrix material was prepared through solid-state synthesis, and the nano-SiO2 ...
Heat channeling in extremely thin silicon-on-insulator devices: A simulation study
(2013)
Silicon-on-insulator (SoI) devices are particularly interesting for thermal management studies as they suffer from severe self-heating because of the very low and isotropic thermal conductivity of silicon dioxide that is ...
Thermoelectric properties of LaNi1-xCoxO3 solid solution
(2003)
The thermoelectric properties of the selected members of the LaNi 1-xCoxO3 solid solution were investigated. The electrical properties of the solution investigated were determined from the doping level. The substitution ...
