Observation of nonlocal ferron-drag thermoelectricity
Takuma Itoh, Takamasa Hirai, Ping Tang +8
The Peltier effect induces a heat current when a charge current passes through a conductor. Since a charge current is conserved at the junction between two different conductors, th…
Reconstruction-Dependent Imaging, Reactivity and Local Reduction of the CeO(100) surface
Kyungmin Kim, Manuel González Lastre, Estefanía Fernández-Villanueva +7
The possibility of mapping the local reactivity and reduction state to the atomic structure of chemically active oxide surfaces opens new avenues for further understanding of catal…
Structural heterogeneity-induced enhancement of transverse magneto-thermoelectric conversion revealed by thermoelectric imaging in functionally graded materials
Sang J. Park, Ravi Gautam, Takashi Yagi +3
Functionally graded materials (FGMs) exhibit continuous property variations that enable unique functionalities and provide efficient platforms for systematic property optimization.…
Trans-scale spin Seebeck effect in nanostructured bulk composites based on magnetic insulator
Sang J. Park, Keisuke Hirata, Hossein Sepehri-Amin +3
The spin Seebeck effect (SSE) enables thermoelectric conversion through thermally generated spin currents in magnetic materials, offering a promising transverse geometry for scalab…
Near-surface Defects Break Symmetry in Water Adsorption on CeO(111)
Oscar Custance, Manuel González Lastre, Kyungmin Kim +7
Water interactions with oxygen-deficient cerium dioxide (CeO) surfaces are central to hydrogen production and catalytic redox reactions, but the atomic-scale details of how def…
High-throughput development of flexible amorphous materials showing large anomalous Nernst effect via automatic annealing and thermoelectric imaging
Sang J. Park, Ravi Gautam, Abdulkareem Alasli +5
This work demonstrates high-throughput screening of flexible magnetic materials for efficient transverse thermoelectric conversion based on the anomalous Nernst effect (ANE). The a…
