The Nernst effect in high-$T_c$ superconductors

, 2005
The observation of a large Nernst signal $e_N$ in an extended region above the critical temperature $T_c$ in hole-doped cuprates provides evidence that vortex excitations survive above $T_c$.

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

Advanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Degradation Mechanisms of Rutile‐Type TiO2 Photoanodes during Photoelectrochemical Water Splitting

Advanced Energy Materials, EarlyView.
Combining operando dissolution measurements with microscopy and spectroscopy characterizations, we reveal different degradation mechanisms of rutile‐type TiO2 photoanodes during photoelectrochemical water splitting. In acidic electrolytes, degradation is inhibited once TiO2 reaches saturation.

Quanta of Nernst coefficients and thermomagnetic EMF

Известия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. The well-known quantum Hall effect observed in two-dimensional current conductors placed in a transvers magnetic field is due to the magnetic quantization of cyclotron orbits of charge carriers, leading to the appearance of Landau levels in ...

Linear Response in Topological Materials

Applied Sciences, 2019
The discovery of topological insulators and semimetals has opened up a new perspective to understand materials. Owing to the special band structure and enlarged Berry curvature, the linear responses are strongly enhanced in topological materials.

Nernst Effect in Magnetized Plasmas

, 2015
We present nanosecond timescale Vlasov-Fokker-Planck-Maxwell modeling of magnetized plasma transport and dynamics in a hohlraum with an applied external magnetic field, under conditions similar to recent experiments. Self-consistent modeling of the kinetic electron momentum equation allows for a complete treatment of the heat flow equation and Ohm's ...

Anomalous Nernst Effects of [CoSiB/Pt] Multilayer Films

Journal of Magnetics, 2013
We report a measurement for the anomalous Nernst effects induced by a temperature gradient in [CoSiB/Pt] multilayer films with perpendicular magnetic anisotropy. The Nernst voltage shows a characteristic hysteresis which reflects the magnetization of the film as in the case of the anomalous Hall effects.

Compact Modeling of Volatile‐Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

Advanced Intelligent Systems, EarlyView.
A volatile‐switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I−V sweeps, SET kinetics, relaxation dynamics.
