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 ...

Giant conductivity switching of LaAlO3/SrTiO3 heterointerfaces governed by surface protonation

Nature Communications, 2016
The interface between two oxide materials can play host to numerous exotic phenomenon. Here, the authors observe a four order of magnitude change in the conductance at a lanthanum-aluminate–strontium-titanate interface controlled by surface protonation ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Structure‐Polarization‐Function Relationship in Oxide Perovskite for Solar‐To‐Fuel Conversion Challenge

EcoEnergy, EarlyView.
Oxide perovskites (ABO3) have emerged as paradigm‐shifting materials for solar energy conversion, uniquely combining ferroelectric polarization, piezoelectric response, and tunable optoelectronic properties. This review comprehensively examines how controlled structural distortions generate built‐in electric fields that overcome ultrafast charge ...

P-type conductivity in annealed strontium titanate

AIP Advances, 2015
Hall-effect measurements indicate p-type conductivity in bulk, single-crystal strontium titanate (SrTiO3, or STO) samples that were annealed at 1200°C. Room-temperature mobilities above 100 cm2/V s were measured, an order of magnitude higher than those ...

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices
