Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics

Advanced Robotics Research, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Frequency dependence of the longitudinal spin Seebeck effect

, 2018
International audienceThe spin Seebeck effect provides an easy way to create and manipulate spin current. Schreier et al. experimentally observed a decrease of spin Seebeck voltage at high frequencies in the yttrium iron garnet/Pt system [Phys. Rev. B 93,

Spin Seebeck effect in nanometer-thick YIG micro-fabricated strips

AIP Advances, 2017
We have investigated the spin Seebeck effect (SSE) generated by current induced-heating in ultra-thin yttrium iron garnet film (20 nm) covered by an 8 nm thick Pt layer.

Low energy dissipation readout of single-molecule ferroelectronic states by a spin-Seebeck signal

Physical Review Research, 2020
Single-molecule magnets (SMMs) possessing bistable states have been considered as promising candidates to realize zero-dimensional (0D) ferroelectrics (FE) and multiferroics (MF) with high storage density. However, how to read or manipulate the FE states

Coupled Vacancy and Phonon‐Scattering Engineering Drive Defect Evolution Toward Multifunctional High‐Performance Bi2Te3 Thermoelectrics

Advanced Science, EarlyView.
ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...

Temperature dependence of the spin Seebeck effect in [Fe3O4/Pt]n multilayers [PDF]

, 2017
We report temperature dependent measurements of the spin Seebeck effect (SSE) in multilayers formed by repeated growth of a FeO/Pt bilayer junction. The magnitude of the observed enhancement of the SSE, relative to the SSE in the single bilayer, shows a ...

Thermoelectric Properties of a Diketopyrrolopyrrole Polymer With Radical Pending Units

Advanced Electronic Materials, EarlyView.
The successful incorporation of TEMPO radicals as side‐chain groups onto the conjugated backbone of an n‐type polymer significantly enhanced the doping efficiency of N‐DMBI via a hydrogen transfer doping mechanism. ABSTRACT Organic n‐type polymers usually suffer from relatively low electrical conductivity which hampers their application as an active ...

Absence of anomalous Nernst effect in spin Seebeck effect of Pt/YIG

AIP Advances, 2016
The Pt/YIG structure has been widely used to study spin Seebeck effect (SSE), inverse spin Hall effect, and other pure spin current phenomena. However, the magnetic proximity effect in Pt when in contact with YIG, and the potential anomalous Nernst ...

Spin Seebeck effect in Y-type hexagonal ferrite thin films [PDF]

, 2017
The longitudinal spin Seebeck effect (SSE) has been investigated using Pt/ferrite bilayers employing two Y-hexagonal ferrites Ba2Zn2Fe12O22 (Zn2Y) and Ba2Co2Fe12O22 (Co2Y) deposited by a spin-coating method on SrTiO3(111) substrates.
