Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...

Superconducting mesa-structures with a spin filtering manganite interlayer

EPJ Web of Conferences, 2018
We report on current transport and magnetism in hybrid superconducting mesa-structures prepared from epitaxial superconductor YBa2Cu3O7-δ and manganite LaMnO3 thin films. Superconducting Au-Nb bilayer was the top electrode.

The preparation and properties of bilayer manganite films

Acta Physica Sinica, 2003
The bilayer manganite film La2-2xSr1+2xMn2O7(x=032)were successfully prepared by pulsed laser deposition(PLD)method.By controlling the parameters of deposition,the fabricated films are of single phase and grown well on two kinds of substrates with different lattice constants.After measurements of transport property,it is found that there is 80K ...

Material‐Driven Neuronal Oscillators and Filters via Active Reactance in CC‐NDR and VC‐NDR Electro‐Thermal Memristors

Advanced Physics Research, EarlyView.
Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Relationship between structure and charge/orbital order in epitaxial single layer Ruddlesden–Popper manganite thin films

APL Materials
Ruddlesden–Popper manganites are strongly correlated, quasi two-dimensional systems with highly tunable functional properties, which can, for example, be controlled by composition, strain, and defects.

Strain effect on resistivity of La0.7Ba0.3MnO3 thin film

EPJ Web of Conferences, 2018
A complex study of the dc and magnetic characteristics of epitaxial manganite films La0.7Ba0.3MnO3 (LBMO) was carried out under conditions of the crystal structure tension caused by a mismatch between the parameters of the LBMO crystal and the substrate.
