Electrically tunable interfacial thermal conduction via electronic structure engineering in / topological insulators
Min Young Kim, Joon Sang Kang, Jangwoo Ha +8
This work provides direct experimental evidence for the role of topological interface states in thermal conduction across a metal/topological insulator junction. It also shows that…
Catalytic effect of plasma in lowering the reduction temperature of
Jaemin Yoo, Dongkyu Lee, Jimo Lee +3
Atmospheric pressure plasma (APP) generates highly reactive species that are useful for surface activations. We demonstrate a fast regeneration of iron oxides, that are popular cat…
Spincaloritronic measurements: a round robin comparison of the longitudinal spin Seebeck effect
A. Sola, V. Basso, M. Kuepferling +16
The rising field of spin caloritronics focuses on the interactions between spin and heat currents in a magnetic material; the observation of the spin Seebeck effect opened the rout…
Magnon-drag thermopower and Nernst coefficient in Fe, Co, and Ni
Sarah J. Watzman, Rembert A. Duine, Yaroslav Tserkovnyak +5
Magnon-drag is shown to dominate the thermopower of elemental Fe from 2 to 80 K and of elemental Co from 150 to 600 K; it is also shown to contribute to the thermopower of elementa…
The effect of the magnon dispersion on the longitudinal spin Seebeck effect in yttrium iron garnets (YIG)
Hyungyu Jin, Stephen R. Boona, Zihao Yang +2
We study the temperature dependence of the longitudinal spin-Seebeck effect (LSSE) in a yttrium iron garnet Y3Fe5O12 (YIG) / Pt system for samples of different thicknesses. In this…
Anisotropic defect-induced ferromagnetism and transport in Gd-doped GaN two-dimensional electron gasses
Zihao Yang, Thomas F. Kent, Jing Yang +3
Here we report on the effect of rare earth Gd-doping on the magnetic properties and magnetotransport of GaN two-dimensional electron gasses (2DEGs). Samples are grown by plasma-ass…
P-type doping of elemental bismuth with indium, gallium and tin: a novel doping mechanism in solids
Hyungyu Jin, Bartlomiej Wiendlocha, Joseph P. Heremans
A new doping mechanism is described, whereby a doping impurity does not simply transfer charge to the bands of a host semiconductor or semimetal, but rearranges the core energy lev…
Enhancement in the Figure of Merit of p-type BiSb alloys through multiple valence-band doping
Hyungyu Jin, Christopher M. Jaworski, Joseph P. Heremans
N-type Bi100-xSbx alloys have the highest thermoelectric figure of merit (zT) of all materials below 200K; here we investigate how filling multiple valence band pockets at T and H-…
