Large phonon-drag thermopower polarity reversal in Ba-doped KTaO3
Mohamed Nawwar, Samuel Poage, Tobias Schwaigert +6
This study reports the observation of phonon-drag thermopower polarity reversal in Ba-doped KTaO3 thin films, mediated by electron-phonon Umklapp scattering. Epitaxial films with d…
Electric field dependent thermal conductivity of relaxor ferroelectric PMN-33PT through changes in the phonon spectrum
Delaram Rashadfar, Brandi L. Wooten, Joseph P. Heremans
In ferroelectric materials, an electric field has been shown to change the phonon dispersion sufficiently to alter the lattice thermal conductivity, opening the possibility that a…
Extraordinary Thermoelectric Properties of Topological Surface States in Quantum-Confined Cd3As2 Thin Films
Wenkai Ouyang, Alexander C. Lygo, Yubi Chen +8
Topological insulators and semimetals have been shown to possess intriguing thermoelectric properties promising for energy harvesting and cooling applications. However, thermoelect…
Magnon Diffusion Length and Longitudinal Spin Seebeck Effect in Vanadium Tetracyanoethylene (V[TCNE], )
Seth W. Kurfman, Denis R. Candido, Brandi Wooten +7
Spintronic, spin caloritronic, and magnonic phenomena arise from complex interactions between charge, spin, and structural degrees of freedom that are challenging to model and even…
Magnetic field-controlled lattice thermal conductivity in MnBi2Te4
Dung D. Vu, Ryan A. Nelson, Brandi L. Wooten +3
Phonon properties and the lattice thermal conductivity are not generally understood to be sensitive to magnetic fields. Using an applied field to change MnBi2Te4 between antiferrom…
