Nanoscale Spin Seebeck Rectifier : Controlling Thermal Spin Transport across Insulating Magnetic Junctions with Localized Spin

, 2014
The spin Seebeck effect is studied across a charge insulating magnetic junction, in which thermal-spin conjugate transport is assisted by the exchange interactions between the localized spin in the center and electrons in metallic leads. We show that, in

Magneto-thermoelectric performance of bulk composite Fe3O4/Pt pellets: Combined spin Seebeck and anomalous Nernst effects [PDF]

APL Energy
In this article, we show the measurement of the magneto-thermoelectric effect (spin Seebeck and anomalous Nernst effects) of bulk composite pellets prepared from nanopowders of Fe3O4 and Pt. We compare structural, magnetic, and thermoelectric data as the

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

Advanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Additive Manufacturing of Ni‐Based Thermoelectric Materials for Waste Heat Recovery

Advanced Materials Technologies, EarlyView.
Thermoelectric generators convert waste heat into electricity but are constrained by conventional fabrication. Here, laser powder bed fusion enables direct printing of customised n‐type Cu60Ni40 and p‐type Ni90Cr10 legs. The assembled module achieves 0.8% efficiency at ΔT = 419 K, demonstrating scalable additive manufacturing of eco‐friendly, design ...
